Problem description

If I enter a big number in the nestedTest form Collect "freezes” after going to the hierarchy view or trying to save the form as a draft. On Android 14 it’s usually ANR or black screen. On Android 10 after saving the form as draft there’s dialog about validating answers that doesn't disappear (I waited 5 minutes) or there’s also black screen (less often than on Android 14 ANRs occur). I guess it’s because of the big number (I tried smaller numbers and it works well) but the form is "stuck” until I kill the app and manage to discard the savepoint. I’m not sure what is the expected result if some actions (e.g. adding too many repeats) in the form take too much time/ are too big.

Steps to reproduce the problem

  1. Go to nestedTest form. nestedTest.xml.txt
  2. In question "number of households” enter a big number e.g. 5000 and go to the hierarchy view or try to save the form as draft.
  3. Kill the app and try to reopen the form (recover the savepoint).

This is a long-standing issue. I don't think we can realistically improve things for a number as big as 5000, unfortunately. Does it work for 500? 200?

Yes, 500 works well.
