Robert,
I had downloaded a new version of the zip file this morning thinking the same thing, but thought I would go through the entire exercise again just to be sure.
In FlexBuilder I removed the eDraw module reference and the widget reference in the config file. Just for good measure I deleted everything in the bin-release and bin-debug folders and rebuilt the project.
Then I cleared the browser cache.
I downloaded a new version of the code and tried the compiled version first -- same results. Then I used the uncompiled code, referenced the mxml file, and rebuilt the project -- same results. At least the problem is consistent.
There were no errors reported when I opened DrawWidget.xml using IE, so I ran the debug tool within FlexBuilder to see if any errors were thrown. When I click on the eDraw Widget, I receive the following warning:
warning: unable to bind to property 'style' on class 'Object' (class is not an IEventDispatcher)
This is the only indication of a problem, no other errors or warnings pop up.
