Hi All,,
I have 2 dropdownlist box in my view. i.e, COURSEGROUP and COURSE. When an entry in coursegroup listbox is selected , the COURSE listbox should be enabled and corresponding entries should be filled into the list items.
I have initially disabled the COURSE listbox.
I'm not using Model class for data binding.
My problem is:
When an OnSelect event occurs for COURSEGROUP list box, the control of program is going back to DO_REQUEST method and displays the same screen as earlier. The control is not entring the DO_HANDLE_EVENT method of controller..
I can also send the code if required.
Please help me out,,
Thanks in advance,,

are you using DISPATCH_INPUT in your DO_REQUEST method?This will then trigger the control to DO_HANDLE_EVENT and passes the onSelect event. Control will come back to DO_REQUEST after processing of DO_HANDLE_EVENT IS done.
Please check by keeping break points at DO_REQUEST and DO_HANDLE_EVENT methods.
Cheers
