Has anybody found a solution to the following problem -
A tab called tab_1 is in a managed solution and deployed to our TEST environment.
Later tab_1 is renamed to tabMeaningful (or deleted and readded with the new name) and then deployed again to TEST.
The result is the form shows both tab_1 and tabMeaningful.
I understand this is because of the layering logic of managed solutions.
Note: it also happens with subgrids and ribbon buttons.
