Path too complex for xmlbeans ("..")

Trying to see if my app is still running with v2
(downoaded around noon today - December, 2nd 2004 - 11:00 GMT)
I encountered the following error : "Path too complex for xmlbeans"

This situation happens while manipulating
an XMlObject (CObject) refering <C></C> inside this XML

<A>
<B>
<C></C>
</B>
</A>

I try to refer my parent (ie B) by doing
CObject.selectPath("..")
and then I get the following error :
Path too complex for xmlbeans

Obviously it was working with v1,
any ideas ?

Thks,
