I have the following problem in CE 5.1.0 .

I have three user modules, the A is ralated with one-to-mane to the other two, B and C.
In Tabs configuration, when I hide the B and C, then the A looses its relation to the other two, B and C.

In other words, if I choose from the list of As, no subpanels of B and C shown.

Thanks,
John
