Exploring the port of an existing Editor to Dltk 0.91 (Eclispe 3.3.1.1/JDK 1.5)

Now to the point of just trying to get the Editor to open, but runinng into the
following -- very confused -- error.
The exception occurs when the editor part control is being created by
EditorReference#createPartHelper at the line "part.createPartControl(content);"
The createPartControl method is actually failing in ScriptEditor#installSemanticHighlighting
on the line:
fSemanticManager.install(this, (ScriptSourceViewer) getSourceViewer(),
getTextTools().getColorManager(), getPreferenceStore());
Except, in debugging, all of the class types are correct. Any idea how to figure
out where the real problem is?
Thanks,
Gerald

Hi Gerald,
Please check what your
SourceViewerConfiguration.getPresentationReconciler() method returns
ScriptPresentationReconciler class.
Best regards,
Andrei.
