Hi,
I assume your query model loads the records from a db? Then persist the new
Myrecord first (via a DAO and/or service layer) and then detach the model
explicitely to let it query a fresh state.
WebMarkupContainer myPanel = new WebMarkupContainer("myPanel");
myPanel.setOutputMarkupId(true);
form.add(myPanel);
final QueryModel model = (QueryModel)getDefaultModel();
final ListView lv = new ListView("rows", model) {
@Override
protected void populateItem(ListItem item) {
// don't pull anything out of models just to place it into
another model,
// otherwise you're just increasing your session size
item.add(new TextField<Integer>("value",
new PropertyModel<Integer>(item.getModel(), "value"),
Integer.class));
}
}
myPanel.add(lv);
AjaxSubmitLink addLink = new AjaxSubmitLink("addRow") {
@Override
public void onSubmit(AjaxRequestTarget target, Form<?> form) {
// let you service layer persist the new record
dao.persist(new Myrecord());
// let the model query a fresh state
model.detach();
if (target != null) {
target.addComponent(myPanel);
target.addComponent(addLink);
}
}
public boolean isVisible() {
// although disdained recently IMHO this is a perfect place to
override
isVisible()
// and be always up-to-date
return super.isVisible() && model.getObject().size() < 10
}
};
addLink.setDefaultFormProcessing(false);
form.add(addLink);
