Providing Default Values in MovieRole

As discussed in "Specifying Default Values for New Enterprise Objects", there are two main ways to specify default values for new enterprise objects without making explicit assignments:

For the Movie class, you specified default values using a display group. This approach is also the more appropriate choice for the MovieRole class, but you'll use the other approach for MovieRole just to see how its done.

  1. Open MovieRole.java in Project Builder.

  2. Add the method, awakeFromInsertionInEditingContext, as follows. 
    public void awakeFromInsertionInEditingContext(EditingContext 
context) {
    super.awakeFromInsertionInEditingContext(context);
    roleName = "New Role";
}

    This method is automatically invoked right after your enterprise object class creates a new MovieRole and inserts it into an editing context, which happens when you use a display group to insert.

Running Movies

 Be sure that all your project's files are saved (including your model file), and build and run your application. Now when a user clicks the Insert/New button on the MovieDetails page, a new MovieRole is inserted, with "New Role" already displayed as the role name.
