Testcase.

Import the attached testcase.

When you generate the handler you will get the following exception:

This blocks the RUI Technical Sample.
Comment 2 Scott Greer CLA 2011-09-26 17:25:38 EDT 
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....
Comment 3 Brian Svihovec CLA 2011-10-17 22:37:00 EDT 
This no longer seems to be happening?
Comment 4 Scott Greer CLA 2011-10-18 15:12:17 EDT 
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?
Comment 5 Brian Svihovec CLA 2011-10-19 12:52:13 EDT 
This appear to be working correctly, so go ahead and mark this one as resolved.
Comment 6 Scott Greer CLA 2011-10-19 15:24:27 EDT 
Brian, that's good news....marking it fixed.
Comment 7 Lisa Lasher CLA 2011-11-09 14:13:24 EST 
This high severity defect was fixed several weeks ago, so I am closing.
