Comment 2 _ potingwu 2008-08-21 17:03:25 UTC 
From org.netbeans.modules.visualweb.designer.jsf.JsfForm.
Comment 3 Peter Zavadsky 2008-08-26 23:46:51 UTC 
The facesModel was not loaded, also there is another exception, pointing to invalid FacesModel instance (with no LiveUnit),
Comment 4 Peter Zavadsky 2008-09-25 18:29:41 UTC 
The problem is now that insync tries to parse the model in another thread, but the system is not synchronized at all
(original impl is not thread safe and worked exclusively in AWT thread - insync, batik, designer).
That seems to be a reason of the exception from the batik, code, it was called from another thread than AWT (thanks to
the changes in insync), while the access is not thread safe.
I am going to attach one suggested fix, that would help in this case, but it would not fix entire problem described above.
