Field mapping doesn't work

Posted on by

Hi colleagues, friends,

today I'm struggling with a nasty little issue that I'd love some support on.

I have this entity called Project. I need to be able to add Team Members (another entity) to this project. There is a (editable, but that doesn't matter, standard shows the same behavious) subgrid with all team members on the project form.
When I click "Add a new project team member" the Project field doesn't get populated even though it's neatly mapped in the relationship.

 

My lights went out when I noticed that via Related > Project Team Members, the "Add a new project team member" button opens the same quick create form with the project field populated as it should!

 

What could possibly cause this?

 

Again, I tried a regular subgrid, with exactly the same outcome.

 

Thanks for thinking along with me.
Regards,
Jeroen
