Hi,
the notify change methods is definitly not a good place to add this
dialog, because it will be triggered from other callers, too.
You need to create your own implementation of the create child actions,
which add the dialog behavior.
Best regards

Again by implementing a custom delete action.

To customize the layout within the editor, you can use EMF Forms. To
customizte the editor itself, you need to implement a custom version of
it. The existing implementation should be a good template for this.
