CC 2015 onDraw Throws Error during Rendering

[joejoe_jack]

I have a ScriptUI Panel with some custom buttons. I use onDraw event to draw the buttons. Works fine except when rendering. I receive an error "Can not run a script while a modal dialog is waiting for response"

Happening only on CC 2015. Try-catch will not fix as that is still scripting. Any workarounds?

I have the exact same issue, and I don't believe there's a way around it, which renders the onDraw callback completely useless.

If we can't use it without errors, why even include it as a possibility?

I have the same problem. I lose the entire rendered interface. When restarted, this error occurs. That is, as I understand it, this is a conflict of modal windows.
