I have what is probably a simple question.
When a diagram is initially loading, or a database update is in progress, I want to disable the palette so the user cannot drag shapes onto the canvas.I've tried a few things, but none have worked.
This will not work for us.
We need to have the palette disabled anytime we perform a webservice call.
Loading a new diagram (when we switch tabs) requires a webservice call. Other actions also required webservice calls.
During these calls, we display a busy signal in the upper right corner, just above the diagram.
So ideally, we want to disable the palette, start our webservice call, and when the call completes re-enable the palette.
Any thoughts on how to accomplish that?
