Hi, Chris, James! I have put some time into this issue and already have commented on it in JIRA. I think I have found the problem and already have hacked up a solution which I would like to elaborate on. However, James, in JIRA the issue is not assigned to anyone and I would like to discuss some class design changes before implementing a fix and submitting a patch. Who is taking care of the RA code? Is this you, James? Should I discuss this issue with you directly?
