Another developer written the custom page, table and list which isn't depend on any standard table. Now, the source code isn't available. Can I extends that page or used that page name in other action name?
Basically, I need to put an action name in the role center with that page. How can I do this?
Obviously you can do that, exactly like you extend a standard page: you can create an extension with dependency from the other extension and then write a pageextension object that extends the custom page you want.
