Hi Martin
Yes, I've tried @SpringBean but I don't like it because I noticed a (not very
big) performace loss when using it; because the dynamicly-created serializable
proxy.
Or at least that seems to me.
IMHO, the proxy is an overwhelming solution, I prefer a combination of
transients and 'if (dao==null) dao = (
((MyApplicattion)getApplication()).getDao());'
Simply if this can be done in another way.
Thanks

Asunto: Re: After/before creation or serialization
Hi,
onInitialize is called just once for any Component. As its javadoc says it
is called some time before the first call of #onConfigure.
#onDetach() is called before passing the Page to serialization but it can
be called at any time and several times per request cycle, so it is not
good idea to do your task there too.
The solution you are looking for is wicket-ioc module. It is the base for
@SpringBean and @Inject support in Wicket. It injects serializable proxy
instead of your real DAO/Service/... So it is very cheap for serialization
and doesn't require your real dao/service to be Serializable itself.
