SharePoint sandbox webpart error by required field validator

I have a sandbox webpart, it works fine until I add "RequiredFieldValidator" control.
It seems that only "CustomValidator" works fine.
I am getting following message:
Unhandled exception was thrown by the sandboxed code wrapper's Execute method in the partial trust app domain: An unexpected error has occurred.

Thanks, Amit

Required to set all required propoerties, for example for a RequiredFieldValidator "ControlToValidate" should be specified. I had suspect that I should specified that before I take a look at how the html page looks like, I was in rush so ran the application and got that error.

I think the following error occurs when a control on the WebPart generates the error,this could be one of the reason:
Unhandled exception was thrown by the sandboxed code wrapper's Execute method in the partial trust app domain: An unexpected error has occurred.
