• Bug Type: Staging

1. Create a new Form with a 'non-required' text field
2. Add Form display portlet to a page, with the created Form
3. Submit the Form with blank fields
4. Modify the Form's field to 'required'
5. Set up Local Staging with Forms enabled

Expected result:

• Import process finish with Success, the exported Form Entry will be imported properly

Actual result on 7.0.x:

• Import process fails, there are error messages in the log about form validation

Actual result on master:

• Form entries cannot be exported at all

A similar behavior is observable when referencing ddm structures with journal too. In that case the import of the journal article would fail due to validation errors.
