Hi,
I am trying to use the zooming capabilities of GEF. I have followed the
Logic example.
I have placed the zoom-in and zoom-out actions in the context menu, but
i am getting the following exception on clicking the 'zoom' actions:

Exception: Failed to execute runnable (java.lang.RuntimeException: class
org.eclipse.draw2d.ScaledGraphics has not implemented this new graphics
function)

Can someone please shade light on the problem?

Hi Snehal,

There is a shape on your diagram that does not support scaling. Do you have
a gradient or background pattern somewhere? The stack trace will give you a
hint.

Cheers...
Anthony
