Hi Cédric,
I was adding a window action instead of an Action itself.
However, when I add Actions with the usage dashboard, they are shown, but empty, without content.
Someone eles has the problem : Dashboard very basics - #4 by herrdeh
Even after restarting the the docker container, since there seems to be intensive cashing of the dashboard for the user, the dashboard windows did not fill with data.
I rebuild my testing environment, installed the dashboard module, and now achieved the result I was expecting, with the Action of module Projects.
But wait: I checked again on the demo database and configured it again with the action lines to pay (sorry I messed up the proper name) and added the action to the user Demo_de’s dashboard.
The Result is
What looks different to the window when acessed via the menu.
So long story short. I fixed my problem thanks to your help with the Action for Project.
But the same effect occurs on the demo database. You might check the demodatabase with login user demo_de and you should find the result.
Regards jakob
