DrawPane doesn't display

[barrettt]

I am trying to run your demo RadialGradientSample, but I can't seem to get the DrawPane to display.

If I comment out the lines:
drawPane.draw() and
layout.addMember(drawPane)
I see the color pickers and slide bar, but if I run it without the commented lines, nothing appears on the screen.

I am running
NetBeans IDE 7.1,
GWT4NB 2.10.5,
GWT 2.4.0,
SmartGWTPro 3.0 (SmartClient Version: SC_SNAPSHOT-2012-03-11_v8.2p/LGPL Development Only (built 2012-03-11)),
on a Window 7 box.

The only messages in the Developers COnsole were:

11:12:07.648:INFO:Log:initialized
11:12:07.951:WARN:Log:New Class ID: 'EditPane' collides with ID of existing Class object '[DataSource ID:EditPane]'. Existing object will be replaced.
This conflict would be avoided by disabling ISC Simple Names mode. See documentation for further information.

Thanks.

I am having a similar issue in JDeveloper. I'm trying to get the shape rotation showcase example working, and only the scrollbar for rotation displays. The DrawPane does not display.

IE 9 64-bit
JDev 11g (11.1.2.1.0)
SmartGWT 3.0

Code below is taken from the Showcase...

You may not have included the Drawing module in your .gwt.xml - see docs on DrawPane.

That was the solution - thank you, Isomorphic!
