Delete Feature causes two commands in Undo Stack [message #1386661]

Hi,

we are using Pattern Approach to create and maintain the Shapes.
and hence extending DeleteFeatureForPattern in the Feature provider.
All (add,move,etc.,) Features function properly in the (Undo/Redo)command stack except delete.
The delete appears as two commands. Update and then Delete.
This caused a glitch in the UI. The Undo of the Update command causes the UI shape
to be removed, but the Delete command is the one that deletes.
However in Redo Stack it appears as one.

Tried the following approach,(did not solve the issue)
*called the updateIfPossible in the execute of a delete feature

Regards,
Nirupama

Hi Nirupama,

usually you should not need to extend DeleteFeatureForPattern (see the
classes's header comment). From within the delete method of your pattern
class you should simply call update.
