In the wicket example of Form Input (
http://wicketstuff.org/wicket14/forminput/
http://wicketstuff.org/wicket14/forminput/ ), I'm looking at the source and
can't make out what's happening with this line:
// display the multiply result
Label multiplyLabel = new Label("multiplyLabel", new
PropertyModel<Integer>(
getDefaultModel(), "multiply"));
I understand what this accomplishes, but I don't understand how. We're
passing this property model the default model of what exactly? I don't get
what it means to pass a property model a sublass of IModel to base itself
off of.
Thanks,
mike

The property model is set formerly to the parent container (form or
panel) by constructor injection.
new Form("id", defaultModel);
or
new Panel("id", defaultModel);
If you check the hierachy of parent classes you can see the
getDefaultModel mthod implementation.
