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.




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.

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"; }

 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
