I took the init() function out from one of the js file and now both of the js file is working fine for the DCT.so which clarifies that my onSaveNameSpecified and onSaveDone was not conflicting to each other.so it was the init() function which was causing the issue.But i still want to know without using "The advanced event registry" suggested by JonathonG , is it possible to use more then one global js( with init() funtion on each js) in any dct?
