Toolset Forms deletes (image) postmeta if field is conditionally hidden in the Form, even if the field has a value saved

Symptoms

Toolset Forms allows hiding/showing fields conditionally using Forms Conditionals.

In case you hide any complex field (e.g. the Checkboxes field) in a Form using any such conditions, submitting such post-editing Form will remove the post meta of those conditionally hidden fields from the database altogether.

Workaround

The only workaround here would be applying custom code that grabs the value of the conditionally hidden field before saving the post using the form. This way, the post is updated again with the same value.

Our Developers are aware of this issue and will try to provide a fix for it in future.
