Yes, i have done debug=true in config.php.
actually if i did some normal change in existing file like i add a new button in Mainpanel class in tool bar of calendar so this button is showing up there. But as i created a new class file EventDialod1.js (Just a copy of EventDialog.js) and using the class GO.calendar.EventDialog1, so i am not able to use this class file of this class. or create this class in other existing file then it's not loading. for that what should i do, that i can include my class files with module and it load with the Modules.
I have also studied Create a Module section but It's not helping me, I have to just add one new file in Existing Module for a new Dialog.
