Bug report #14162
Cannot set parent to NULL in relation reference widget

Although the ``Allow null value`` option is checked if a child already has a parent, I cannot set that parent to NULL from the form.
Tested under Debian Stretch, QGIS 2.12.3 and Master.
I have attached data so that the issue is easily reproduced.

Hi and thanks for the info.
I understand that when the user has checked the
Use a read-only line edit instead of a combobox box, he has the opportunity to set the parent to NULL by clicking on the X.
However, I am considering that as a workaround because if the Default setting (combobox) is used, and the
Allow null value option is checked then there is no way to select the NULL value from the combobox, and the user is restricted to the selection between other parents.
I'm attaching a GIF so that it's clearer.

Confirmed in current master (4c63c85cca6b33150c2af67895a2083dc69a7c5d), but the behaviour changed a little:
Now the combobox does not contain a
NULL entry at all, while before it contained one that was not selectable.
