Hi all,

When I want to create a new element in my model, and use a graphical
editor with it, the following happens:
- 1. Select the CreationTool in the Palette
- 2. Move the CreationTool to the editor area to create a new element
- 3. Press the ESC key (Cancel creation).

In this case the model has already changed (the element has been created
and added to the model). I need to undo the model creation. How can I do
that?

Thanks,
Balint PERSICS

you mean you didnt clicked the mouse and then also the model is created?

if this is the case then you should better check where you are adding the model.

try to do the add operation in your execute method of your command and not in your edit policy..,

ESC key is preserved to make PaletteView's default tool(selection tool)
be selected.
