I think this is because of the listitem model. the listitem model biggybacks off the listview model so for every row it makes a call.
you can wrap the PropertyModel with some sort of a CachingModel that would cache the value returned from the PropertyModel for the duration of the request.
Something like this:
class RequestCachingModel implements IModel {
private IModel delegate;
private transient Object cache;
private transient boolean cached=false;
public RequestCachingModel(IModel delegate) {
this.delegate=delegate;
}
public Object getObject(Component c) {
if (!cached) {
cache=delegate.getObject(c);
cached=true;
}
return cache;
}
public Object setObject(Component c, Object o) {
delegate.setObject(o);
detach();
}
public void detach() {
cached=false;
cache=null;
}
....
}
hope this helps-Igor
