[Grid] AdvancedColumnCollector exception

[Corepex]

Hi Team,

If you open the data-object folder with the ID 695 you get several endpoint errors.

See:
http://localhost/pimcore-studio/api/data-object/grid/available-columns?classId=EF_FD&folderId=695
http://localhost/pimcore-studio/api/data-object/grid/configuration/695/EF_FD

I added the following lines to check if that already fixes the issue:

if($classDefinition !== null) {
    $classIds[] = $classDefinition->getId();
}

That brings then the following error:

Best guess would be that back in the days Category was named ProductCategory and this name is still in there.
Please have a look and check why that occures and how to prevent it.

Searched a bit more and found out that the crossSellingCategory is the issue.
Just select Category in the Allowed classes and save the definition - then everything works again.

@Corepex we added the check to verify that class definition exists. As you said, the class definition was renamed at some point and now its still incorrectly referenced in the crossSellingCategory field. Please create a follow up in the respective bundle/demo as it needs to be fixed there.
