WTP build I-I20080313113126.
UOE happens in the WTP WSDL, XSD and XML editors as well. Content assist doesn't work after this exception.
(In reply to comment #2) > UOE happens in the WTP WSDL, XSD and XML editors as well. Content assist > doesn't work after this exception. Does this have to be triggered by the WPE? I'm not seeing it with just the XML Editor in I-20080313162923.
I see it, now. Upping severity because it causes content assist to stop working.
Thanks, Nitin. It looks to me like 222673 is likely rooted in the same core issue (although stack trace shows a slightly different code path).
Thanks, Ian. Fix released. Keith and Ian, can you retest with at least org.eclipse.wst.xml.ui v200803140234?

Going through the same test scenarios, I cannot reproduce the problem using the I-I20080314073909 build.
Verified fixed with build I-I20080314073909. Thanks, Nitin!
