Hi, I just saw, that I'm not working with the beta 2 but with the snapshot. In beta 2 the NPW is thrown at line 1038 (in snapshot at line 1041). The line is:
String renderKitId = context.getViewRoot().getRenderKitId(); And looking at the variables in debugging mode says, that the viewRoot is null. Sorry for the confusion :) Of course I don't mind to open a JIRA issue :) PS: I know tomahawk isn't even supposed to work with myfaces 2, but in generally it does. This one here is the only compatibility problem I found (...for now ;) ) Matthias -------- Original-Nachricht -------- > Datum: Tue, 23 Mar 2010 15:44:32 +0100 > Von: Jakob Korherr <[email protected]> > An: MyFaces Discussion <[email protected]> > Betreff: Re: UIComponentBase.java - context.getViewRoot() returns null > 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?
