[news.eclipse.modeling.gmf] Re: Problems with Duplicate action

[Thomas Beyer <thomas.beyer81@xxxxxxxxxxx>]

Hi Mario,


my solution below:

1. Create a new class called DuplicateAnythingCommand (see attached file).

2. In your generated XXXBaseItemSemanticEditPolicy, add the following 
lines to your generated <getCommand>-method as follows:
public Command getCommand(Request request) {
	[...]
	Command result = super.getCommand(request);
	if (request instanceof EditCommandRequestWrapper) {
		IEditCommandRequest ier = ((EditCommandRequestWrapper) 
request).getEditCommandRequest();
		if (ier instanceof DuplicateElementsRequest && result == null) {
			//call your new DuplicateCommand
			return new ICommandProxy(new 
DuplicateAnythingCommand(getEditingDomain(), (DuplicateElementsRequest) 
ier));
		}
	}
	[...]
	return result;
}


Does the trick for me.

HTH
Regards, Thomas
