More guice serialization problems

[Edgar Merino <do...@gmail.com>]

Hello once again,

    wicket-guice integration has been working good for me, but I needed 
to get some injected services in classes that were not Components, so I did:

Injector injector = ( (GuiceInjectorHolder) 
RequestCycle.get().getApplication().getMetaData(GuiceInjectorHolder.INJECTOR_KEY)).getInjector();
injector.injectMembers(this);

    This arises serialization problems with the Guice injector, although 
I'm not keeping a reference to the injector... this should be because 
the actual injected service is not handled by a wicket ioc proxy. Igor 
suggested salve, I've been doing some reading about it but haven't try 
it yet, but wouldn't it just throw the same exception when using salve 
since it's not a proxy either? or maybe this won't happen because salve 
would inject a local dependency (inside a method) when needed? can 
anyone clarify this for me (and maybe many others with the same doubt)?

Thanks again for the help,
Edgar Merino

salve removes fields and performs just in time lookup of the dependency. so
no serialization errors and your instances take up less ram.

as far as wicket's guice support goes you should really do this
InjectorHolder.getInjector().inject(this) - this will inject proxies instead
of actual dependencies.
