When you promote a feature of an embedded bean in the Promote Features window, you can use a default feature name produced by VisualAge. If you do not want to use the default feature name, you can change the name.
The default feature name is a combination of the name of the embedded bean and the name of the feature you are promoting. This identifies the bean that implements the feature, which is helpful if the composite bean contains more than one bean with the same feature. Then, when you connect to the feature, you can tell which embedded bean it belongs to.
For example, if you promote the enabled property for a bean named YesButton, the default composite bean feature name is yesButtonEnabled).
