[Newbie]Session lost in an AjaxFallbackLink onClick()
Hi,
When in an AjaxFallbackLink's onClick(), the object I retrieve from my
session is null, even if in my form constructor the object was properly
retrieved :
public CreatureForm(String id, HibernateObjectModel object ) {
super(id, object);
Creature sessionCreature = ((DemoUser) ((DemoSession)
getSession()).getUser()).getCreature() ;
System.out.println("Creature name in the form : " +
sessionCreature.getName());
System.out.println("Creature location : " +
sessionCreature.getCurrentXP());
add(new AjaxFallbackLink("aLink"){
@Override
public void onClick(AjaxRequestTarget target) {
Creature sessionCreature = ((DemoUser) ((DemoSession)
getSession()).getUser()).getCreature() ;
System.out.println("Creature name in the form : " +
sessionCreature.getName());
System.out.println("Creature location : " +
sessionCreature.getCurrentXP());
}
}
In the onClick, I get a java.lang.NullPointerException...
What do I do wrong ?
Thanks in advance

where is your NullPointerException?
Creature sessionCreature = ((DemoUser) ((DemoSession)
getSession()).getUser()).getCreature() ;
The Session or the user?

Ok, it's done : http://www.nabble.com/file/p18044618/issueTest.tar.gz
issueTest.tar.gz .
BTW, it's an Databinder app. Everything will be launched in memory. When you
start, you'll be invited to enter the creature's name, then you'll be
redirected on the creature page where you'll be able to click on a "+" link
to increase its hitpoints... it's the link which fails.
BTW, doing this quickstart, I've noticed that it was working a bit better
when, in the DemoApp init, I was adding manually the creature to the user
(see the TODO). However, in this case, the update I do on the model aren't
kept, so it doesn't work properly neither...
Thanks again
bye

Try & reproduce it in a QuickStart, so someone else can investigate?

I'm planning to display messages when my creature data are changed, maybe it
could help. If you've any other ideas of things I could try, let me know !

I'm sorry but I don't get where I could erase it.
I add the AjaxFallbackLink in the same form and in the page I display the
creature's name and some of its characteristic and everything is rightly
present. It's just in the AjaxFallbackLink's onClick() that it fails...
I did the following try in between :
- I rightly get the user and its content. So this part is properly working
- I've tried the form's onSubmit, and there I get some part of my creature
data but not all of it (I get the name but not others attributes...).
Weird isn't it ????

It's the sessionCreature which is null, I get NullErrorException when trying
to do something with it.
My getSession().getUser() went without any hurdle.
