    When you add a categorisation property to an existing custom module, when you go to edit and existing item or add a new one it breaks.

    If you add the classification at the time of creation (before activating) it is fine.

    Steps to reproduce (Latest version):

    - Create custom module
    - Activate it
    - Add classification property and save changes
    - try and create a module item

    Hello Roberto,

    I was not able to recreate the behavior you describe on a clear 7.0 project. Here is a video of the behavior on my machine. Feel free to correct my steps if necessary.

    If you are experiencing this behavior on your end, feel free to send us a support ticket where we can investigate this in further depth on your particular solution.

    Regards,
