[News.eclipse.technology.gmf] DestroyElementRequest

["Irina Sudnik" <irina.sudnik@xxxxxxxxx>]

Hello,

I have a problem with the DestroyElementRequest. I  want to check some 
condition just before deleting an element from diagram so that 
DestroyElementCommand may be not executed. I use approveRequest() in 
FlowEditHelperAdvice (Flow is the diagram name):

@Override

            public boolean approveRequest(IEditCommandRequest request) {

                        if (request instanceof DestroyElementRequest) {

                                   if.....return true;

                                   else return false;

}

return true;

            }

Unfortunately this method will be called with DestroyElementRequest even if 
no elements were deleted. How can I solve this problem?

Thanks in advance
Irina
