Musachy Barroso resolved WW-2736.
---------------------------------
Resolution: Cannot Reproduce
I just tried this on IE 7 and the token example in showcase and works as
expected. Maybe the synchronization bug fixes fixed this. If you are still
getting the NPE with trunk (2.1), feel free to re-open it and add more details.
