I have a Product Option field set up as checkboxes that are checked by default. If I go to the form's page directly, everything is fine. The checkboxes are checked.
However, if I have another (non-Gravity Forms) form on a different page (action = the form's page, method="post"), the checkboxes on the Product Option field will no longer appear as checked.
It doesn't seem to matter what is included in the $_POST variables. The checkboxes are simply no longer checked by default. This is the case, even if I use gform_pre_render to make sure ['isSelected'] = 1.
Any ideas for a workaround?
