Unhandled System.NullReferenceException in XML Editor

hi all,

 

when editing xml document based on particular set of schemas, keep getting following in errors tab:

 

unhandled 'system.nullreferenceexception' in xml editor

object reference not set instance of object

 

things going fine until did inheritance in 1 of schemas in set (complextype has complexcontent extends complextype)...  seems i'm toast.

 

the problem occurs when open xml document based on schema.  opening other documents based on other schemas in set works fine...

 

any ideas?

 

thanks

james
