Model model = new Model(map)

getObject()

return new List(map.entries())

ahh ok change this
new ListView("list", new ArrayList>(map.entrySet()))
{
thats wrong you can't keep Map.Entry objects in a arraylist.
why not keep the map yourself?
new ListView("list", new Model(map) {

no Maps are serializable
and yes your problem is the final keyword before that variable.
because you make it final so that you can reuse that in an (anonymous) inner
class
and then that Entry is placed in the session because it becomes a member of
that inner class
just remove the final keyword (a
So the problem isn't the final keyword but the fact that Maps aren't
serializable, right?

You shouldn't keep entry objects like that then it will become members and

Hi,
I just ran into problems with a List view. The Model used for this is
actually a Map so I put in a entrySet() from the map in the ListView:
new ListView("list", new ArrayList>(map.entrySet())) {
public void populateItem(final ListItem listItem) {
final Map.Entry entry = (Map.Entry)
