Error while trying to edit a View

Error while trying to edit a View

Hi team ZOHO
 
I have just started to recieve the following error when I try to edit one specific View in my application.
 
 
[ServletException in:/jsp/edit/view/viewedit.jsp] null'
 
 
I can still edit other Views without any problems and users can still access the view in question, I just cant edit it.
 
Any help greatly appreciated.
 
Regards
 
Simon
