Chapter 2 Enhancing Your Application

10. In the object browser, click application.

There is an entry in the second column for the

allGuests application variable

you created. This entry appears in the Main component as well, since

application variables are accessible from anywhere in the code.

If you click

allGuests, you’ll see in the third column an entry for count. This is

a standard method that returns the number of objects in the array.

11. Click

count and drag to the center rectangle to bind it to the WOString’s

value attribute.

12. Save the GuestList component.

You need to do one more thing so that the GuestList page now displays

when the user submits the form.

13. Go back to Project Builder and view the source code for

Main.java. Replace the

return statement in the submit method with the following code:

return application().pageWithName("GuestList");

allGuests. count represents the number

of objects in the array. Drag to bind it to the

WOString.
