I don't have steps to repro. this exception. Found it while testing JSF functionality.

Comment 2 Nitin Dahyabhai 2010-06-03 10:35:45 EDT

In this case the stack trace is good enough.  The changes for bug 236311 added the attribute's name, as a string, as a value during adapter notification.  This is the first time in an XML-based DOM where the value is neither null nor itself a DOM Node.

Created attachment 173326 [details]
proposed patch, might need to be scaled back

Comment 6 Nick Sandonato 2010-07-06 11:17:42 EDT

Patch looks OK to me.

Comment 7 Nitin Dahyabhai 2010-07-12 10:17:06 EDT

Untargeting pending being able to write a JUnit or having a reproducable scenario.  I can't figure out how this could actually happen--AttrImpl can only call notify on an Element and yet the adapter is only installed on a Document.

Changes released to 3_2_Maintenance and HEAD.

Thanks, Raghu. Rakesh seems to already have a fix for this lined up: Bug 331084.
