Re: [Wicket-user] Playing with models:)/wicket.extensions.markup.html.form.palette.Palette;
Ill like to take
you up on the discussion.
I see the following pros
and cons with this approach:
Pro setObject:
Allows the user to
implement logic into the model If so desired
Special conversions to satishfy wicket components needs, for
example, wicket component needs one list but you have three, so join them
in the get operator and split them in the set
Logic, etc disable other components, notify
Hold the standard implicitly directed by having a set object method
Feels the right wayJ
Con setObject:
Performance could be slightly improved?
I do think that that
using setObject on the model is something that always should be done; it
creates a lot of flexibility and why have setObject if not to use it, if not it
will only cause confusion.

components whose model is
backed by a collection do not always call setobject() because they work on the
collection directly so there is no need to call
Collection c=model.getObject();
c.clear();
//refill c
model.setObject(c); == NOOP
and also in wicket there is a guard
component.setObject(c) {
if (c.equals(model.getobject()) {
//noop
} else { //clone for version tracking; model.setObject (c); }
}
the above saves on unnecessary cloning.
just a few things to be aware of, whether or not we should call setobject()
anyways is still up for discussion.
i kinda think we should even though sometimes the objects are the same.

When is setObject supposed to get called, Cause I only see it get called
during
construct?
Whenever a (form)component has to update it's modelcontents. Or if
you call setObject explicitly of course :() Typically, a component
update is done by Form, which visits all it's children and calls
updateModel on them.

Re: [Wicket-user] Playing with models:)/wicket.extensions.markup.html.form.palette.Palette;
yes you are right.But in 1.2 this couldn't be done because of some code that was sitting in the way (modelChanging/changed double called and so on)in 2.0 we pretty much have fixed that part i believe. now. Have to look at it further.
