What is the setPage() method?  From what class?

Are you trying to do a form wizard(multiple pages using one
DynaValidatorForm)?  If so, I have something like that.  But I had to
override the reset() method in DynaValidatorForm class.--I am still not sure
if this is the most elegant way. (don't have time to investigate further)

Let me know if I should post my code.

Subject: DynaValidatorForm and Multi-page Forms


 Since nobody answered my previous posting, I'd just like to know if
 anyone has been able to get DynaValidatorForm with multiple pages to
 work without having to use the setPage() method. If so, can you please
 post an example?


 Thanks!

Yes. This is it exactly.

In struts-config.xml I have:

 form-beans
form-bean
	   name=dynaRegistrationForm
	   dynamic=true
	   type=org.apache.struts.validator.DynaValidatorForm	
	.
	.
	.
	form-property name=page  type=int/
	.	
	.
	.
   /form-bean
 /form-beans

And in the jsp's I have the typical hidden field:
	.
	.
	.
	html:form method=GET action=/action/register
  html:hidden property=page value=2/
	.
	.
	.

But the page will not validate correctly unless I call explicitly the 
setPage method for the DynaValidatorForm in the Action class, like so:
	
	DynaValidatorForm info= (DynaValidatorForm) form;
	int foof = -1;
	try{
	foof = Integer.parseInt(request.getParameter(page));
	info.setPage(foof);
	}catch(Exception e){
	if(!(e instanceof java.lang.NoSuchMethodException))
		log.error(e.getMessage(),e);
}
	
	ActionErrors errors = info.validate(mapping, request);
	

If I do not put the above in the Action code, the info.getPage() always 
returns zero, so the page is not validated since I have no page=0 in the 
appropriate places in validation.xml. With the above the first page gets 
validated correctly but the second also tries to validate every field 
that has page=2 in validation.xml AND page=1 too, which all fail since 
those parameters are not being submitted. It is almost like it is 
forgetting that they were set on the first page. Perhaps the trouble 
is that the DynaValidatorForm is not being saved in the session? I 
should not have to do this myself. Right? If you have this working, then 
by all means post your code.


Thanks a bunch!

Oh I see.  In my code, I am validating using the plug-in validator.  You are
validating in the action class.  I haven't tried the things you are doing.
Anyone else tried this?

I am using the plug-in validator too. At least I think I am :) I was 
just following the examples that come with Struts 1.1b, specifically the 
 struts-validator webapp with the MultiRegistrationForm example with 
the exception that they are not using DynaValidatorForm.
