Repeat through selected items

Support

Hi,
Is it possible to select a number of items from a select_multiple list,
then build a repeat that will iterate through all the selected items?
I'm using SurveyCTO.
Thanks a lot!

Hi Maria,

Yes, certainly, this is possible. For the repeat-count of the repeat group,
you would call count-selected() (as in "count-selected(${multiplechoice})"
when multiplechoice is the name of your select_multiple field). Then,
within the repeat group, you could have the following fields:

this_selection: this would be a calculate field with the calculation
expression "selected-at(${multiplechoice}, position(..))", again where
multiplechoice is the name of your select_multiple field. This takes your
current position in the repeat group ("position(..)") and fetches the
selection value (from the name column of your choices sheet) for the
associated selection.

this_selection_label: this would be a calculate field with the calculation
expression "jr:choice-name(${this_selection}, '${multiplechoice}')", just
to grab the label associated with the selection value -- in case it's
helpful for reference in notes or labels. (This jr:choice-name() function
was recently supported in SurveyCTO and recently fixed in ODK. See
https://code.google.com/p/opendatakit/issues/detail?id=854&sort=-id.)

As a side note, I was just discussing a related process with another
client: taking a set of select_multiple choices and randomly selecting one.
For this, you can use fields defined like the following:

randomdraw: this would be a field calculated with the calculation
expression "random-once()". (We recently added random-once() to SurveyCTO
to avoid the possibility of random numbers being re-drawn when saved forms
are edited -- but, in standard ODK, you would call the standard random()
function. See recent discussions on this subject, in this community group.)

randomselectionindex: this would be a field calculated with the calculation
expression "round(${randomdraw}*count-selected(${multiplechoice})+0.5,0)"
where multiplechoice is the name of the select_multiple field. This
essentially takes the random draw between 0 and 1 and scales it to be a
whole number between 1 and the number of selections the user made in the
select_multiple. (Obviously, this won't work well for 0 selections. You
will want to make your later follow-up questions relevant only when
"count-selected(${multiplechoice}) > 0".)

randomselection: this would be a field calculated with the calculation
expression "selected-at(${multiplechoice}, ${randomselectionindex})". Given
the selection number in randomselectionindex (e.g., 1 for the user's first
selection), this returns the actual value of that selection (from the name
column of the choices sheet).

randomselectionlabel: this would be a field calculated with the calculation
expression "jr:choice-name(${randomselection}, '${multiplechoice}')", just
to grab the label associated with the selection value randomly chosen in
randomselection -- in case it's helpful for reference in notes or labels.
(This jr:choice-name() function was recently supported in SurveyCTO and
recently fixed in ODK. See
https://code.google.com/p/opendatakit/issues/detail?id=854&sort=-id.)

I hope that's helpful.

Best,

Chris

Hi Chris
When I'm in select_multiple, is it possible to choose one or more items and disable what you don't need to choose because you have already the correct ones in other to minimize errors in data collection.
Thanks

Hi,

I couldn't get this approach to work. I get an error in xlsform of
ava.lang.ArrayIndexOutOfBoundsException:
1 >= 0 in xlsform which seems to be caused by the calculation selected
-at(${multiplechoice}**, position(..)). Is this surveyCTO only?

Does position(..) get the position of the selected option in the select
multiple question that is being processed or the position in the loop?

regards

Neil

Hi Jean,

You can filter the list of options that appear, of course, based on
earlier-selected options. But you can't show them in the list but have them
disabled. There is no way to individually disable choice options (while
leaving them there on the screen).

Sorry!

Hi Neil,

We also discovered that selected-at() could be extremely picky, giving that
error whenever the passed index was invalid for the current list of
selections -- and that, during validation, it would reject basically any
index. Therefore, for some time you had to do something like...

if(position(..)-1 < count-selected(${multiplechoice}),
selected-at(${multiplechoice}, position(..)-1, -1)

...to be sure never to pass an invalid index to selected-at(). In this
example, if position(..) is somehow out of range (which it will be during
validation), it returns -1 rather than calling selected-at().

Note that I used position(..)-1 rather than position(..). I believe that
my original suggestion was off in that position(..) is 1 for the first
iteration, 2 for the second, and so on, but selected-at() wants 0 for the
first, 1 for the second, etc. Thus, the correct thing to pass to
selected-at() is position(..)-1, not position(..).

As soon as we discovered it, we removed this pickiness from SurveyCTO, so
that it wouldn't give these errors on validation or require elaborate if()
statements. We also submitted that change to the community, and I believe
that it was rolled into ODK's JavaRosa, and thus into its ODK_Validate, and
thus into its XLSForm. If you're using the online version of XLSForm and
it's still giving this error, let us know. Maybe it's just that the online
XLSForm hasn't been updated.

Thanks for catching this.

Best,

Chris

I have not yet updated XSLForm and released an updated ODK Validate that
should address this issue.

Thanks Chris,

That updated (older style) formula works nicely with the current xlsform.
There was a minor typo, a bracket was missing:
if(position(..)-1 < count-selected(${multiplechoice}),
selected-at(${multiplechoice}, position(..)-1), -1)

very impressive!

regards

Neil

Hi Neil,

We also discovered that selected-at() could be extremely picky, giving
that error whenever the passed index was invalid for the current list of
selections -- and that, during validation, it would reject basically any
index. Therefore, for some time you had to do something like...

if(position(..)-1 < count-selected(${multiplechoice}),
selected-at(${multiplechoice}, position(..)-1, -1)

...to be sure never to pass an invalid index to selected-at(). In this
example, if position(..) is somehow out of range (which it will be during
validation), it returns -1 rather than calling selected-at().

Note that I used position(..)-1 rather than position(..). I believe
that my original suggestion was off in that position(..) is 1 for the first
iteration, 2 for the second, and so on, but selected-at() wants 0 for the
first, 1 for the second, etc. Thus, the correct thing to pass to
selected-at() is position(..)-1, not position(..).

As soon as we discovered it, we removed this pickiness from SurveyCTO, so
that it wouldn't give these errors on validation or require elaborate if()
statements. We also submitted that change to the community, and I believe
that it was rolled into ODK's JavaRosa, and thus into its ODK_Validate, and
thus into its XLSForm. If you're using the online version of XLSForm and
it's still giving this error, let us know. Maybe it's just that the online
XLSForm hasn't been updated.

Thanks for catching this.

Best,

Chris

Hi,

I couldn't get this approach to work. I get an error in xlsform of ava.lang.ArrayIndexOutOfBoundsException:
1 >= 0 in xlsform which seems to be caused by the calculation selected
-at(${multiplechoice}**, position(..)). Is this surveyCTO only?

Does position(..) get the position of the selected option in the select
multiple question that is being processed or the position in the loop?

Hi Maria,

Yes, certainly, this is possible. For the repeat-count of the repeat
group, you would call count-selected() (as in "count-selected(${**multiplechoice})"
when multiplechoice is the name of your select_multiple field). Then,
within the repeat group, you could have the following fields:

this_selection: this would be a calculate field with the calculation
expression "selected-at(${multiplechoice}**, position(..))", again
where multiplechoice is the name of your select_multiple field. This takes
your current position in the repeat group ("position(..)") and fetches the
selection value (from the name column of your choices sheet) for the
associated selection.

this_selection_label: this would be a calculate field with the
calculation expression "jr:choice-name(${this_selection},
'${multiplechoice}')", just to grab the label associated with the selection
value -- in case it's helpful for reference in notes or labels. (This
jr:choice-name() function was recently supported in SurveyCTO and recently
fixed in ODK. See https://code.google.com/p/
opendatakit/issues/detail?id=**854&sort=-idhttps://code.google.com/p/opendatakit/issues/detail?id=854&sort=-id
.)

As a side note, I was just discussing a related process with another
client: taking a set of select_multiple choices and randomly selecting one.
For this, you can use fields defined like the following:

randomdraw: this would be a field calculated with the calculation
expression "random-once()". (We recently added random-once() to SurveyCTO
to avoid the possibility of random numbers being re-drawn when saved forms
are edited -- but, in standard ODK, you would call the standard random()
function. See recent discussions on this subject, in this community group.)

randomselectionindex: this would be a field calculated with the
calculation expression "round(${randomdraw}count-*
selected(${multiplechoice})+0.**5,0)" where multiplechoice is the name
of the select_multiple field. This essentially takes the random draw
between 0 and 1 and scales it to be a whole number between 1 and the number
of selections the user made in the select_multiple. (Obviously, this won't
work well for 0 selections. You will want to make your later follow-up
questions relevant only when "count-selected(${**multiplechoice}) >
0".)

randomselection: this would be a field calculated with the calculation
expression "selected-at(${multiplechoice}**,
${randomselectionindex})". Given the selection number in
randomselectionindex (e.g., 1 for the user's first selection), this returns
the actual value of that selection (from the name column of the choices
sheet).

randomselectionlabel: this would be a field calculated with the
calculation expression "jr:choice-name(${**randomselection},
'${multiplechoice}')", just to grab the label associated with the selection
value randomly chosen in randomselection -- in case it's helpful for
reference in notes or labels. (This jr:choice-name() function was recently
supported in SurveyCTO and recently fixed in ODK. See
https://code.google.com/p/**opendatakit/issues/detail?id=**854&sort=-idhttps://code.google.com/p/opendatakit/issues/detail?id=854&sort=-id
.)

I hope that's helpful.

Best,

Chris

Hi Jean,

You can filter the list of options that appear, of course, based on
earlier-selected options. But you can't show them in the list but have them
disabled. There is no way to individually disable choice options (while
leaving them there on the screen).

Sorry!

Chris, Neil, this is very helpful.

I was looking to solve exactly this problem, and your solution looks very close to working for me (still can't Validate it, but never mind that).

My problem is that the jr:choice-name(${this_selection}, '${multiplechoice}') values do not change. That is, I loop x times (based on count-selected(${multiplechoice})), but the this_selection_label value does not change change in each loop iteration. This could be an issue with the position or with how I've set things up. Perhaps some code would make this more clear (note that I'm very new to this, so might be making some very obvious mistakes):

So the idea is that the user can select multiple people that they have discussed their HIV status with (in CDH2, say Mother and Father), then Collect will loop CDH3 2 times, displaying Mother the first time and Father the second.

However, what happens is that Mother is displayed in both iterations of the loop (instead of Mother then Father). I suspect this is because I have done the calculate in the wrong place? Or am not using variables where I should?

Do any obvious things jump out to you?

Thanks in advance,

Hi Colin,

For the position(..) to work properly, it needs to be called from within
the repeat group itself. Thus, CDH2_position and CDH2_name both need to be
inside the repeat group (CDH3_group, I believe). If you give that a shot, I
think that it might work.

Best,

Chris

Thanks Chris,

That's a good call, something that I had tried - however, it doesn't fully solve the problem. Now, the person (ie Mother) no longer shows up in the CDH3 label.

So the output on the tablet looks like:
CDH3. Before you told your that you are HIV-positive, how did you expect this person to react?

I may have missed something re referencing?

Sorry, Colin. I'm not sure what's going on there. Maybe the CDH2_group
reference isn't working from within CDH3_group? I'm not an XML expert as we
deal almost exclusively with XLSForm (where there are far fewer things that
can go wrong).

I would suggest starting with a super-small, super-easy form with just the
bare minimum of groups and complications, and see if you can get something
to work. Then, if that works, very carefully sort out what's different in
your case that's not working.

Best,

Chris

Thanks Chris,

That's a good call, something that I had tried - however, it doesn't fully
solve the problem. Now, the person (ie Mother) no longer shows up in the

So the output on the tablet looks like:

I may have missed something re referencing?

That's a good idea Chris - I've pared it down as best I can and learned some interesting results.

In order to confirm that position and name are working/not working, I gave them their own outputs as well (good ole' println).

What I learned from that is that position is working - it tracks the data value from the multiselect (1, 3, 4, etc). What is not working is the name, ie the result of the jr:choice-name(/data/CDH2, '/data/CDH2').

I assume from the docs that choice-name takes a result from a previous select (an int, essentially) and a reference to the select. If that is the case, I'm baffled why it can't deal with the generated position value.

Code below:

      <CDH2/>
      <CDH2_sum/>
      <CDH3_group>
        <CDH3_position/>
        <CDH3_name/>
        <CDH3/>

Dear all,

I need to include a repeat with on a multiple selection list, as described in the correspondence above. But I can't figure out how to make it work in my excel. Is there someone who would be willing to send me an example in excel that shows how this can work so that I can use this as a reference in my excel? I also attached my own excel if that is more easy to change. Would be great! Many thanks in advance.

Kind regards,

Ed

Hi Colin,

It sounds like you're making progress. Maybe just try passing a fixed
selection value as the first parameter into jr:choice-name() to see if that
works? If CDH2 is a multiple-select, then you need to call selected-at() to
get one of the selections to pass as the first parameters to
jr:choice-name() -- you can't just pass the entire list of selections.

Best,

Chris

Hey Chris,

Got it! Your last post really pointed me to the issue - I was passing in the list of selections, not one specific one (kind of dumb mistake, in the end, as expected).

Thus,
WRONG:

RIGHT:

Thanks so much for your assistance on this. Made my life (and the life of the prof I'm working for) much easier!

Excelent guidance, thanks a lot this is what I was looking for!
