FormLogicError Failed to execute 'evaluate' on 'XPathEvaluator'

[sergiousme]

Hi @Xiphware

I’ve noticed that this nested group does not allow any relevant conditions. Initially, I thought the problem was due to referencing question outside the group, which would require precise indexed-repeat syntax, as suggested, but it seems like it’s not allowing to add any relevant conditions. but just some calculations.

I also reviewed this post from @Josh and tried changing the operators in the conditions with no results.

XLS export failed

Hi @Vladoos, that’s great! I’ve spent some time looking into this issue and battling to reproduce it with a simple form (I can reproduce it with your form). However I have found that the problematic cell is L81 in your form “Guide d’enquête Parcelle” (your relevant value for the repeat group Conso_Inter). If I change this from ${ci}="oui" to the equivalent of ${nb_ci}!="" it no longer gives me the error. Can you make this change, redeploy and then try editing again?

Additionally, I came across previous issues regarding nested repeat-groups here:

XLS export failed

Hi @Vladoos, sorry, yes that was an unfortunate typo — I’ve edited my previous message with the correct variable name. Hmmm that’s concerning… this is a strange one. I’ll continue investigating. I’ve noticed recently that doubly nested repeat groups sometimes have strange issues so if you can avoid them in future forms that would be safer

So, is this an unresolved issue?

However, I will give the proper indexed-repeat syntax another try.

On the other hand, I’ve managed to avoid the error by making the following changes:

Previous xlsform (with errors when trying to edit some submitted forms)

Current form

Changes made:

1. In yellow. Removed all relevant conditions. As previously mentioned, the error remains with any type of relevant (not just those referencing questions outside the group)
2. In green: Modified the calculation formula to avoid referencing questions outside the group.
3. In blue: avoided referencing ${_edad_especie} in line 73. Otherwise I keep getting the same error:

Trying to manage this one, I thought I could be related to the calculation formula, so I changed it to check if that was the problem

The conclusion is that the error persists when referencing ${_edad_especie} in line 73, regardless of the calculation formula.

Funny thing: lines 68 and 69 are doing the exact same thing, that is, performing a calculation and then printing the result in a label, but those lines are not causing any trouble so far.

This is getting pretty esoteric,
