org.apache.xmlbeans.impl.values.XmlValueDisconnectedException error message

Hi! On certain Soap WSDL definition, we get a dialog with just only the text 'org.apache.xmlbeans.impl.values.XmlValueDisconnectedException' when trying to generate documentation.

 

I can't find the reason why; on certain WSDL files it just works fine, while on others I get this message. I can't find major differences between these files. Can anybody give a hint what is going on here?

 

Grts,

Mark.
