Created on 7 May 2024, 8 months ago

Problem/Motivation

Get an error on RegisterForm.php when try to apply any condition with the Conditional Fields module.

Steps to reproduce

Install and enable Registration module.
Install and enable Conditional Fields module.
Create an Registration event.
Create some fields ( at least two ).
Go to Conditional Fields, and add an condition on the event, using the fields ( ex. make one visible if the other is checked )
You get a blank page with error message.

Thanks for the post. I have not been able to reproduce this so far with a boolean field controlling a registration field on a node. Can you confirm more of your setup details - is this with only Drupal core, entity registration, and conditional fields - or are other modules in the mix.
