.ClassCastException for DefaultRDFProperty

ulrich thye
Hi,

I get the Error:

 java.lang.ClassCastException: edu.stanford.smi.protegex.owl.model.impl.DefaultRDFProperty
        at
edu.stanford.smi.protegex.owl.ui.properties.OWLObjectPropertySubpropertyRoot.getTopLevelObjectProperties(Unknown
Source) at edu.stanford.smi.protegex.owl.ui.properties.OWLObjectPropertySubpropertyRoot.<init>(Unknown Source) at
edu.stanford.smi.protegex.owl.ui.properties.OWLObjectPropertySubpropertyPane.createRoot(Unknown Source) at
edu.stanford.smi.protegex.owl.ui.properties.OWLSubpropertyPane.<init>(Unknown Source)
...
...

(full Error below)


The Property widget failed.
It should a simple reason, because I never get this error before.

Any hints?

Regards

Ulrich
