implementing undo actions [message #463651]

Hi every one,

i want to implement undo facility.I am trying to do it in the following
steps.

Actually i have a editTreeOperation in which i have overridden execute
,undo and redo methods.So to get this going in my context menu i have
written an action class.In the run method of this action class i have my
code which i sent in my previous thread and this time i am not passing
null parameters in the
operationHistory.execute method.

Trying in this way is not working for me.call is going to constructor of
edittreeoperation but not going to execute method.

Some how the above steps are not working.Can anyone suggest me where iam
going wrong?

Thanks in advance
Tammareddy.
