Hi,
I think that the method is called quite often because it is used to
calculate the feedback of the mouse.
What happens is probably that whenever you move the mouse, the diagram
computes a new feedback for the cursor by verificating whether the host
EditPart understand the request (by checking the result of
getCreateElementAndViewCommand).
Place a breakpoint on this method to see the invocation stack.
