ComponentEditPolicy [message #160695]

Originally posted by: sd10046.lanet.lv

ComponentEditPolicy -> createDeleteSemanticCommand has

....
Command semanticCmd = getHost().getCommand(editCommandRequest);
if (semanticCmd != null && semanticCmd.canExecute()) {
CompoundCommand cc = new CompoundCommand();
cc.add(semanticCmd);
return cc;
}
return createDeleteViewCommand(deleteRequest);

Am I right that even if command can't be executed, view will be deleted
anyway?
Is it correct behaviour?

Ty,

Yes, your conclusion seems correct. If the logic in
shouldDeleteSemantic() is correct, then I would think that if you can't
delete the semantic element that the view should not be deleted.
However, a client may be depending on this behavior as it is now. Is it
causing you a problem?

Regards,
Cherie
