Summary

The snippet doesn't work when the dropdown field choices are not set when the form renders. If choices are populated later based on another field selection, it doesn't work. We need to ensure to re-render the logic with gppa_updated_batch_fields for updated fields.

A quick summary screencast of testing this update:

@saifsultanc I was waiting on a customer to reply before merging #762 but I went ahead and merged it since it will conflict like crazy with this PR.

With the latest version of the snippet, if you put the GPPA listener inside the window.<?php echo __CLASS__; ?> = function() { and call gwDisableDuplicates accordingly on the freshed fields, I think that'll do.

This looks solid. It looks like you need to rebase this with https://github.com/gravitywiz/snippet-library/blob/master/gravity-forms/gw-prevent-duplicate-selections.php as there is currently a merge conflict.

You might have to start a new branch based off of master and bring in your changes manually.

More specifically, it looks like you need to bring in the gform_post_conditional_logic behavior, the gppa_updated_batch_fields addition, and whatever else you see fit.
