Building the WDA Application 12.2
to declare the same sort of data, this time in the Context tab in the component
(program) controller.
In this application, you’re going to have three structures: an input structure (with
two fields so that the user can search for monsters by name or by number), a table
of monster headers, and a table of monste r items. The first two will be used on
the main screen and the last one when th e user is looking at an individual monster
record.
Navigate to the COMPONENTCONTROLLER node in your application. Move to the Context
tab, and you’ll see a little ball labeled CONTEXT. Right-click this rubber ball,
which keeps bouncing back to you, and choose Create 폷 Node.
In the screen shown in Figu re 12.6, you do not need to do anything; just accept
all the default settings. (If you are curious what they all mean, (F1) help is actually
helpful here—especially with respect to the Singleton field, where you are
pointed to a blog that basically says, “Nev er switch this on ever or the universe
will explode.”) Since you do not need to change any setting, just click the Add
Attributes from Structure button.
