Implementing custom delete action [message #59293]

Hello,

I am trying to implement a logic where the deletion of an element from the
editor depends on certain condition.

From the XXXTypeItemsemanticEditPolicy, i could make this check in the
getElementToDestroy() method. Even though the reference to the element
exists, the shape is removed from the editor. How would i implement my own
DeleteAction on an element.

Thanx,
Ganesh

Ganesh,

Can you return an unexecutable command in that editpolicy? This should
disable the action.
