Hi friends,
In one of our parent node, we are supposed to add only one
child, and if the user try to add another child, we need to show a
YES/NO dialog to replace the previous child or not.
How can we pop up a YES/NO dialog on adding a child node.
Thanks and Regards biju

Hi Friends,
Its fixed by overriding doExecute method in XXXCreateCommand, if dialog
is to be shown before the model is updated which is given below.
If the dialog is to be shown after the model is updated we need to
overriding XXXCanonicalEditPolicy#handleNotificationEvent to show the
MessageBox.
Thanks and Regards biju
@Override
protected IStatus doExecute(IProgressMonitor monitor, IAdaptable info)
throws ExecutionException {
int result=0;
if(XXXDiagramEditorPlugin.getInstance().getWorkbench().getDi splay().getActiveShell()!=null){
MessageBox messageBox=new
MessageBox(XXXDiagramEditorPlugin.getInstance().getWorkbench ().getDisplay().getActiveShell(),SWT.OK
| SWT.CANCEL |SWT.ICON_WARNING);
messageBox.setText("Warning !!!");
messageBox.setMessage("The Slot can contain only one port. If you
add another one ,the existing one will be replaced");
result=messageBox.open();
}
if(result==SWT.CANCEL){
Status status=new
Status(Status.CANCEL,XXXDiagramEditorPlugin.ID,"Cancel");
return status;
}
return super.doExecute(monitor, info);
}
