[jboss-user] [JBoss jBPM] - Re: Strange class cast exception when changing node assignme

[ij_dett]

Hi Ed,

as I mentioned before the class cast exception is thrown in the last line of this method. It is thrown in the explicit casting statement - the expression being returned.
return (DocumentFactory) singleton.instance();

And here comes the funny part: 

If I inspect singleton.instance() in the debugger, I see and can access a valid instance of org.dom4j.DocumentFactory.

If I inspect (DocumentFactory) singleton.instance() the class cast exception is thrown - even in the debugger.

I simply do not understand this behavior ...

Cheers,
Ingo
