Chapter 3 Working With Dynamic Elements

In the ﬁgure, if you choose the entity CarPackage as the variable’s type, the

following code gets added to your source ﬁle:

/** @TypeInfo CarPackage */

protected EnterpriseObject myCarPackage;

The variable myCarPackage is declared as type EnterpriseObject. The comment

/** @TypeInfo CarPackage */ is a structured comment that WebObjects Builder

uses to identify the entity associated with the object. It is then able to display

the attributes in the object browser as shown here:

Conﬁguring the Display Group

A display group must be conﬁgured in order for it to be created and initialized

automatically when the component is initialized. Display groups are

instantiated from an archive ﬁle (with the extension .

woo) that’s stored in the

component. You shouldn’t edit .

woo ﬁles by hand; they’re maintained by

WebObjects Builder.

Choose an entity from the project’s

models to create an enterprise

object based on that entity.

Choose this item to create a

display group object.

The browser displays the

attributes of the entity

(CarPackage).
