....further to the above I have also spotted an additional issue.
I am also using the MB Group inside a MB Frontend Submission form.
When using the NEW 'clone_empty_start' => true,
attribute within the MB Group settings any sub-field within the group which has the 'required' => true,
attribute set gets an error validation BEFORE a clone has even been added/created? This prevents my MB Frontend Submission form from being successfully submitted!
The Required Fix
=================
Sub-fields within an MB Group that have the 'required' => true,
attribute set should NOT be validated until a NEW clone has been added/created.
Steps to Reproduce
===================
1) Create a MB Group with sub-fields.
2) Within the MB Group settings use the 'clone_empty_start' => true,
attribute.
3) Within the first sub-field in the MB Group set the 'required' => true,
attribute.
4) Fill out ALL fields within an MB Frontend Submission Form (So there are no other errors) but DO NOT add a MB Group Clone.
5) Attempt to submit the form and you will see that it is not possible and the "Please correct the errors highlighted below and try again." error message is shown.
6) Then add a new MB Group Clone - You will see that the first sub-field is highlighted RED and throwing an error validation?
Again, I assume this is a bug that will be rectified shortly?
I look forward to the fix 🙂
