Hi Jean, Thanks for your information. I am using deleteColumn in my application. I will check the behavior once by changing it to use deleteColumns as you suggested. But is there any difference in the CP hooks for a delete request.?? Because, in my CP I have implemented preDelete() and in order to keep my CP generic for any client request, is there any other hook on the CP so that I can process the delete requests accordingly.?? Also, can you tell me the exact class file which has this logic to check for the time stamp for a delete request.??

Vinay, can you please confirm the client call you are doing?
