I don't know what i'm doing wrong. I have a abstract detachable model:
private abstract class OfferListModel extends LoadableDetachableModel{
@Override
protected Object load() {
String stateAsString = stateDropDown.getModelObjectAsString();
Integer year = (Integer) yearDropDown.getModelObject();
String userAsString = userDropDown.getModelObjectAsString();
if (StaticComboLists.OFFER_STATE_ALL.equals(stateAsString)) {
stateAsString = null;
}
if (StaticComboLists.USER_FILTER_ALL.equals(userAsString)) {
userAsString = null;
}else {
userAsString = getSignInSession().getUser().getLogin();
}
OffersListParameters parameters =
new OffersListParameters(userAsString, year, stateAsString);
ClassifiedOffersList offersList =
offersService.findOffers(parameters);
return offersList;
}
}
And eight implementations of it, like this one:
private class BeingPreparedOfferListModel extends OfferListModel{
private static final long serialVersionUID = -1772413039827980131L;
@Override
protected Object load() {
ClassifiedOffersList offersList = (ClassifiedOffersList)
super.load();
return offersList.getBeingPrepared();
}
}
Each instance is used like this:
BeingPreparedOfferListModel beingPreparedOfferListModel =
new BeingPreparedOfferListModel();
beingPreparedContainer =
new DisabledIfEmptyMarkupContainer("beingPreparedContainer",
beingPreparedOfferListModel);
beingPreparedContainer.add(new
beingPreparedOfferListView("beingPreparedListView",beingPreparedOfferListModel));
Where the ListView has a reference to a detachable model, and
DisabledIfEmptyMarkupContainer has a reference also to the DetachableModel:
public class DisabledIfEmptyMarkupContainer extends WebMarkupContainer{
private static final long serialVersionUID = 8749215642567364820L;
private LoadableDetachableModel model;
public DisabledIfEmptyMarkupContainer(String id, LoadableDetachableModel
model) {
super(id);
this.model = model;
setOutputMarkupPlaceholderTag(true);
}
@SuppressWarnings("unchecked")
@Override
protected void onBeforeRender() {
super.onBeforeRender();
if (((Collection) model.getObject()).isEmpty()) {
add(new VisibilityFalseAttributeModifier());
}else {
add(new VisibilityTrueAttributeModifier("block"));
}
model.detach();
}
}
Is something wrong that i can't see?
