Trouble updating ListEditor with a detachable model
Hi, I'm trying to use the ListEditor component from the Wicket in Action blog (). I'm giving it a PropertyModel that points to "parent.children" where parent is a LDM that loads a 'parent' from the database. It displays properly however when I update the TextFields added to the ListItems and try to save the parent, I get the following persistence exception "org.hibernate.NonUniqueObjectException: a different object with the same identifier value was already associated with the session". I get the feeling that this is due to the way the ListEditor handles the model update. What would be required to adapt it to my usage?

Listeditor
Hello friendly folks, I'm experimenting with the ListEditor as introduced at http://wicketinaction.com/2008/10/building-a-listeditor-form-component/. After implementing a move up/down functionality (see http://gist.github.com/245506), I'm getting problems as soon as I add TextFields to a ListItem. The textfield values do not change, although shuffling around the backing list seems to work. As EditorButton doesn't process the form, each textfield seems to keep it's raw input instead of the updated model value. Does anybody see my hopefully blatant error?

Re: Listeditor
the point of the editor is that it is transactional. eg when you create it the first thing it does is copy the model list into its storage. if you edit the model before submitting the form the listeditor will not reflect these changes because it operates on the internal copy of the list... -igor On Mon, Nov 30, 2009 at 7:47 AM, Steffen Dienst steffen.die...@gmail.com wrote: Hello friendly folks, I'm experimenting with the ListEditor as introduced at http://wicketinaction.com/2008/10/building-a-listeditor-form-component/.
