On the customer screen (AR301000), we are trying to add some extra contact fields for the customer. We just need to have a selector where we choose the contact, but we keep getting an error message about the selector not having a callback event.


After research, the ‘ctl00$phG$tab$t0$s0_s1_f2$’ just corresponds to where the field is located on the screen. The field is a UDF added on from the Customization Projects->Data Access section.


I have been looking for a while and cannot find how to make/implement a ICallbackEventHandler or why the target cannot be found. Any assistance would be appreciated.
