I have a working Wicket [v6] application with Guice [v3] - I have used
dependency injection for repository operations right now and I want to
expend it into using services that are session scoped (one per user's
session). I have read through official documentation, various blog posts and
questions
Thanks, I will give it a try :)

Why would there be a difference between local and deployed versions?
And won't it negatively affect performance?

Hi,
I have a form with labels that use PropertyModel. They work fine when I test
them locally - when I click on submit button I get proper refreshed values
in labels. But when I deploy my app it does not work, I still get old
values. Where can be the problem? I am using Wicket 1.4.17 and deploying
I'd say it's mostly a cache.
>From estimates I can say that 80-90% of the time data will be read-only.
Only remaining 10-20% will be data manipulation.
My current implementation is that I use setters on data in Session and then
persist whole User. Like that:

I have a problem with designing authentication and session properly. I asked

instances, not memcache or things like that. And I don't have to do load

could happen probably with big traffic and longer inactivity from user] I

can skip getting data from db and serve data faster...

My last attempts to fix my session and advices here made me thinking if my

Getting whole entity is good in my case. User can modify only his data and
no one else can even access or see it. It speeds up things too.
Anyway, how do you invoke the rest? Without static you of course get
"non-static method cannot be referenced from a static context" compilation

Yeah, no idea why Static is there, must be some leftover from early code.
It's good to have someone else take a look at your code and point the
obvious :) I will check if it solves my problems.

Hi,
I have really serious problems with my sessions - or rather getting and
displaying data with it. It works great when tested locally, but when
deployed to GAE it acts weird. In bad way. I have no idea if it's wicket or
GAE issue, but maybe I can get some hints here.
Problem is that:

Hi,
I am trying to make an ArrayList, populate it and then display them [and do
other stuff later, but I did not get so far]. It does not work though, so
what I am missing?
My code looks like that:
...
ArrayList house_cost = new ArrayList(5);
...
[adding some data here]
[form]
I have nothing else really, just same more of same stuff, only a Form with
Labels, TextFields and submit method.
Anyway, deprecated NumberValidator.minimum(0) method works without any
problems, are there any disadvantages of using that?

So maybe someone could just show me working RadioChoice code with OnSubmit

Hi,
I want to limit users to check exactly 2 options out of X. How can I do
that? I'd also like it to switch last chosen one to new one, if user has
already picked 2 [so it'd deselect last one and choose another, instead of
not doing anything at all].
