Hello all,
I have a question on how to get a repeat group to filter based on an
earlier multiple choice question (this is for commtrack supply chain if
that makes a difference).
Question 1 - lookup table on a list of Programs. Returns a single program
id
Question 2 - repeat group to a fixture on the list of products. Works
until I attempt to reference the program for filtering from question 1
Query expression on the repeat group:
Works: instance('products')/products/product/@id
Doesn't:
instance('products')/products/product[./program_id=current()/../../../question1]/@id
Thoughts? It seems like the repeat group gets built out at the time the
form loads, not at the time that the repeat group is presented to the user.
Thanks!

Stew,
Unfortunately you are correct that the repeat group gets built out when the
form loads, and not during form entry. This is a necessary step to ensure
that there is internal consistency in the repeat structure. Say the
multiple select has 4 choices, and you choose all 4, then fill out all 4
iterations. You then remove choice 1 and 3 from the multiple choice
question, it's hard to convey to the form what data goes away.
The form builders tend to handle this is to handle any in form filtering
by expanding the repeat group fully, then adding a group to the inside of
each, which has a display condition tied to the multiple choice answer.
That ensures that the repeat filters correctly, but also conveys to the
form what to do if the multiple choice answer changes within the context of
the form itself.

Ok - Thanks for letting me know. I will give the technique you describe a
shot and see if I can make that work for me.
Cheers,
