Is there any fix for this?
thanks,
Simon
Very hard to tell, but I guess something related to client-side scipts of the third party control not correctly updated to the client (e.g. RadComboBox client script not registered by the control itself after callback). Unfortunately this is something that I believe is in the third party control and I am not sure we are able to address it.
Why don't you use our own IG WebCombo control demonstrated here:

It is tested and integrated with WARP and will provide better results.
