Choose Composite Exception

RCP Developer 2.7.1 w/SWT Designer 6.4.1:

Attempting to use a Composite as per the Designer Guide results in exception and I can not use this feature:

Looks like a problem with the org.fvjc.homeword.ui.internal.composites.TestComposite class.

Make sure that your classpath is correct and that the class is compiled (check that a .class file exists).

[frankc01]

Eric,

I've verified that the class is built without error. It is in the classpath as well. One thing to note is that for this Plug-In I am using the JDK 1.6.0_02 system libraries.

Make sure that you are running Eclipse with the same JDK version.

JDK 1.5 may not be able to read/load classes compiled with JDK 1.6.

That worked, thanks

[frankc01]

Ok, maybe I talked to soon

It would appear that if I add DataBindings to the composite then a host of different exceptions occur.

Is this a known limitation? Otherwise I will post the exception.

[Eric Clayberg]

We need to see a test case and yoru entire Eclipse ".log" file.
