I was trying to achieve this task: I need to develop a widget to be used on the third page of a form.. ..and that widget should be able to collect the inputs of the previous two pages (one with a combo box, one with a date) and send them to an external App, using a Bundle, to have them processed and retrieve a result to store in the form.
While I was able to create a custom widget and complete the last part (starting an activity for result and bringing external data - a double - into ODK).. ..I am very puzzled about
HOW CAN I GET DATA FROM OTHER - PREVIOUS - PAGES of a form so to be able to sent them out using a custom widget.
Can anyone give me an hint?
I am in a hurry.. ..but I can pay for the support.(Paypal)

Marco,
If you want to do this in Java, take a look at the
FormHierarchyActivity. It shows you how to iterate through the form
with the form controller. Alternatively, you can do it at the form
level by having a note prompt on the page you are on that has the
default value of ${previous_value}.

Thank you for the hint.
I feel the form level is not enoutgh as I have to retrieve in the third "page" both the values of the first and the second. ${previous_value} would provide me just the second's.
I will dig in the FormHierarchyActivity code and let you know!
