Re: mi first app deployed with wicket
make sure the project packaging is set to 'war' so maven will put the
required libs in the WEB-INF/lib.

Re: Storing entity object in session - how to do it?
cant you inject the DAO's to the listeners in the moment you create and attack the listeners to your application? If you have the Injector at that moment, you could even pull your listeners from the Injector, no? On Wed, Oct 7, 2009 at 5:21 PM, Jeffrey Schneller wrote: > Thanks.

Re: ModalWindow and LazyLoading Exception
while i couldnt identify which object is throwing the
lazyInitialization, the problem is probably that the entity is not
associated with the hibernate session. On the request that opens the
ModalWindow you must either reload or reatach the entity

Re: Old instances of a page remain in memory (apparently) forever
you can check the javadoc for WeakReference, but basically
WeakReferences hold the reference until a full gc occurs
