> MyClass is in a jar which is added to the classpath of the Process Project. Saving throws an event loop exception in Error Log View with the following stack.
> Caused by: org.eclipse.jface.util.Assert$AssertionFailedException: null argument;
> at org.eclipse.jface.util.Assert.isNotNull(Assert.java:150)
> at org.eclipse.jface.util.Assert.isNotNull(Assert.java:126)
> at org.eclipse.jface.viewers.StructuredViewer.assertElementsNotNull(StructuredViewer.java:577)
> at org.eclipse.jface.viewers.CheckboxTreeViewer.setCheckedElements(CheckboxTreeViewer.java:431)
> at org.jbpm.gd.jpdl.deployment.IncludeInDeploymentTreeViewer.setCheckedElements(IncludeInDeploymentTreeViewer.java:61)
> at org.jbpm.gd.jpdl.deployment.DeploymentForm$17.run(DeploymentForm.java:635)
> at org.eclipse.swt.widgets.RunnableLock.run(RunnableLock.java:35)
> at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchronizer.java:123)
> The problem is, that DeploymentForm.getElementsToCheckFor() does not respect that MyClass returns null for getCompilationUnit(). As a consequence, setCheckedElements is called with null in the Object[].
