Thank you guys for your feedback. First I moved to a list-mapping in hibernate, but as I am not so familiar with setting up indices with hibernate (or how to change existing schema), I secondly used bag-mapping as Wilhelmsen suggested.
On Java side I can use now an ArrayList and in Wicket frontend I can access it with index like "memberships[0]". -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/How-to-bind-object-in-Hashset-to-CompoundPropertyModel-expression-tp3521031p3526385.html Sent from the Users forum mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
