Although the Q2 SP1 release (2011.2.915) is live for almost 2 months you are actually the first one to report this issue after it was fixed. I have tested the code provided by Marco in an earlier post in this thread, but was not able to reproduce the issue with the SP1 release. I also contacted our developers and they confirmed that we have NOT reverted the fix provided before. Based on that I would suggest that you open a formal support ticket and send me a small sample that demonstrates your scenario. This way I will be able to debug it locally and advise you further.
All the best,
the Telerik team
