Say you create a custom attribute. Normally it should be stored in the ODF_CA_<OBJECT> table.
Say then something goes wrong at it is not created in that table, though it appears on the list of attributes for that object in administration.
That is not the way it is supposed to be.
So you flush your server cache and your browser cache, but it is still there and still not in the ODF_CA_<OBJECT> table.
Where from is it coming to the list of attributes?
