Hi Dan,
I got quite far, to the extend that I was able to render the choices in a
drop-down list, but I *still* had the original input field as a free-form
entry box.
While trying to address this, I got stuck again.
Anyway!
If ComponentFactoryScalarAbstract#createComponent, I have some
code (currently commented out) that looks like this:
public final Component createComponent(final String id, final IModel<?>
model) {
final ScalarModel scalarModel = (ScalarModel) model;
// TODO: This is where the ValueCollection panel gets created.
final List<ObjectAdapter> choices = scalarModel.getChoices();
if (choices.size() > 0) {
return new ValueCollection(id, scalarModel);
} else {
return createComponent(id, scalarModel);
}
}
The point is that if a property of any of the regular scalarModel types is
found to have some choices, then instead of creating the normal
component (e.g. StringPanel), the factory creates a ValueCollection
(ok, the name can be changed).
As I see it, this value collection simply needs to render a the value type
as a dropdown list...
But I'm getting stuck trying to synchronise the HTML and the wicket
viewer code in ValueCollection.
I'm going to stop here for a while, but would appreciate it if you could
uncomment the block in ComponentFactoryScalarAbstract, above,
and have a look at my ValueCollection.java & html.
I deleted what turned out to be unneeded changes to the
ComponentFactoryListDefault.java, ComponentType.java, etc, and
deleted the unneeded ValueCollectionFactory.java.
Regards,
Kevin
