Hello,
I am trying to design a nested form, like the household and household member form. I noticed that without adding the model sheet I get an error "database.convertSelectionString:unrecognizedelementPath: " but the documentation is thin currently and I am not able to figure out the error. After adding the model sheet, I don't get the saved instance of the nested form.
Could you please explain the need for model sheet, whether it is required and how it affects my form design or its storage?
Thanks for any help,
Ajinkya
(this is an ODK 2.0 question)
If you are developing multiple forms for the same table, then you currently
must ensure that all the non-session-variable data fields used by any of
those forms are defined in each form. This is one of the purposes of the
model sheet -- to allow you to declare data fields that are not referenced
in the current form, but that are present in the underlying data table.
The other purpose is for defining session-variables (data fields that are
never persisted to the data table).
In the next release, this requirement will be relaxed, and you will only
need to ensure that the form whose form_id matches the table_id defines all
of the data fields.
When developing forms, you will need to "Purge Database" in the Application
Designer whenever you add or change the data type of a data field.
