Hi Pieter,
I don't use Hibernate, but db4o. The principle however might help you.
I inject my factory methods into my pages using Spring (but that is a
minor detail) and when I make a change to a domain object, I always
store the object first before reloading the page (or in this case,
rendering the ajax changes). When the page reloads, it loads the
modified object from the database. This is important to also ensure
your domain objects are persisted otherwise, they might still hang
around in wicket, but might not be stored in the db.
So you need to do something like
public void onClick(AjaxRequestTarget target){
employee. addAccount(new Account());
employeeFactory.store(employee);
...
}
Rgds,
Pieter
