non-Session Object for From Submission
hi devs,
I have a from which contains some fields: Whole form is reterived by a bean
class say USERINFO if i persist this USERINFO getter setter in session,
@Persist("session")
public abstract USERINFO getUSERINFO ();
public abstract void setUSERINFO (USERINFO USERINFO );
it works ok.
but if don't persist USERINFO in session , like this
public abstract USERINFO getUSERINFO ();
public abstract void setUSERINFO (USERINFO USERINFO );
on submitting form (@tacos:AjaxForm) the error occurs like
"target is null for setProperty(null, "zip", 2)"
(which is USERINFO.zip) i think main class object set to null on
submitting.
plz help me

I don't know exactly how AjaxForm works but it might be that it rewinds
the form on submission so with that code your USERINFO object won't be
set to a non-null value.
Also have a look at the client:page persistence scope. That way you can
persist the object on the client side as long as the user stays on the
same page.

Hi devs,
thanks for your replies
i am already doing some thing like this in pageBeginRender
public void pageBeginRender(PageEvent event) {
if (event.getRequestCycle().isRewinding()) {
return;
}
if(getUSERINFO () == null){
setUSERINFO (new USERINFO("1","ABC","XYZ"));
}
}
but error:
"target is null for setProperty(null, "zip", null)"
remians there if i persist USERINFO in session its OK, but i think in
normal JSP application we need not to persist Whole form content in session,
session just need to use for some long retainable info.
any idea from you will be helpfull for me.

Similarly, I use an @InitialValue annotation to set it to a function
call, like this:
@InitialValue("myDefault")
public abstract String getFoo();
public String getMyDefault() { return "Hello"; }

Well, you can initialize it to a non-null value during pageBeginRender
