Asnwered my own damn question, didn't I? That's what happens when you spend
20 minutes typing up a question for a mailing list ... :)
What I was missing: in the initBinder() method, instead of
binder.registerCustomEditor(Place.class, ppe);
it should be:
binder.registerCustomEditor(Place.class, "places", ppe);
I guess if you don't specify which field of the Object you wish to bind to,
it tries to bind to all of them, or the entire Object. Nope, that won't
work.
Anyway, so it seems to be working in so much that if I choose 3 Places in
the multi-select, in my ApplicationController, after casting my command
Object:
Application application = (Application) command;
application.getPlaces() lists all 3. If I only select 2, it lists two. BUT
it's not saving! All other fields get updated but not Places. The
applicationplaces table still has the data from the sample-data.xml.
Something fishy is definitely going on because in my applicationlist.jsp, If
I associate 2 Places with an Application (using sample-data.xml), that
Application shows up twice in the list of Applications. If I assign 3
Places, it shows up 3 times. Hmmm ...
I already listed my mapping for Application. I don't have a mapping for
Place because I don't need to know which Application a Place is assigned to.
Is my mapping somehow wrong? Could that be messing up the save and the list?
Thanks,
Bob
