This blocks the RUI Technical Sample.

I changed the handler into a library, disabled JS gen and enabled Java gen to prove that this problem also exists in Java;  consulting with Jeff to get a common fix....

This no longer seems to be happening?

It's been awhile;  I can't recall whether this was the bug where Jeff made a change to both generators to at least fix the immediate symptom but not the problem.....does the code actually work as expected?

This appear to be working correctly, so go ahead and mark this one as resolved.

This high severity defect was fixed several weeks ago, so I am closing.
