Locking: RowAlreadyLockedException: Could not acquire lock

Initial behaviour:
--------------------------------------------------------------
I have the kfz-DB and a window with a table and a formular.
I´m using the EXTRAS-Table.

I enable the lock in the formular.
Then i click on the 5th line in the table and I get the lock
for the record.
--------------------------------------------------------------

Real behaviour:
--------------------------------------------------------------
When I click in a second running program on the same record
an Exception is thrown:

Expected behaviour:
--------------------------------------------------------------
No Exception is thrown. Only the formular is disabled until
the lock of the other is out of date.
