i think a LoadableDetachableModel would be good. it is attached once
per request and the data is held for the duration of the request. you
can have a sync block inside load() where you would copy the list from

One way could be to not update the model until you are attaching
again, or - kind of the same principle - update the model from the
buffer on detach. You still need some more synchronization though: the
attach/ detach models need to be synchronized in that case, and you
want to do it it such a way
Spoke too soon... that doesn't work and I see why. Let me think more to

So more like the Swing's single thread policy... In that case, how do I
update model when I receive model data asynchronously? Does Wicket has
something like EventQueue.invokeLater() or EventQueue.invokeAndWait()?
