Hi,
Unfortunately there is no tomahawk port for MyFaces 2.0 available yet, so
this might be a compatibility problem.
I traced the Exception down and found out that it happens, because the
RenderKitFactory returns null for the RenderKit here, see the code from
UIComponentBase:
String renderKitId = context.getViewRoot().getRenderKitId();
RenderKitFactory rkf = (RenderKitFactory)
FactoryFinder.getFactory(FactoryFinder.RENDER_KIT_FACTORY);
RenderKit renderKit = rkf.getRenderKit(context, renderKitId);
Renderer renderer = renderKit.getRenderer(getFamily(),
rendererType);
In the last line renderKit is null and thus we get a NPE.
Do you mind opening a JIRA issue for this? This would be really great.
Thanks!
Regards,
Jakob
