RE : iterator tag
you may also test if the *brand new* collection is defined with the logic:present and logic:notPresent tags... thomas. -Original Message- From: Yansheng Lin [mailto:[EMAIL PROTECTED] Sent: Monday, September 08, 2003 6:14 PM To: 'Struts Users Mailing List' Subject: RE: iterator tag You sure? 'cause normally what I got is just nothing if the list is empty. If the collection you are iterating over contain null values, the loop will still be performed but no page scope attribute (named by the id attribute) will be created for that loop iteration. You can use the logic:present and logic:notPresent tags to test for this case. However, the *brand new* collection has to be defined somehow, i.e., itself cannot be null.

I don't use a load method but I think you're right. Basically, if I'm breaking this down correctly, if someone is using Dispatch/LookupDispatch Action and the struts validator, they would need 1 ActionMapping to call in order to load the page (and it's dispatch method on the action class) as well as 1 ActionMapping for each of the submission possibilities they had on their JSP... i.e., if you wanted to validate 2 subsets of fields on the page, you'd have an actionmapping for each of them. yes Isn't the struts-config going to get quite cluttered and harder to follow if this is the pattern used? it depends on how many actionMappings you need.

RE : RE : Validator and Dispatch Actions
if you want to use different validation rules with the validator you
have to declare different action elements in your struts-config.xml file
(using the same action class if you want).
another means is to validate your form in the methods of your action
class as propose Koni in the mail sent on the list Monday, August 25,
2003 8:04 PM:
struts-config.xml:
actionpath=/logon/action/logon
type=test.web.struts.action.logon.LogonAction
name=logonForm
scope=request-- !!!
validate=false -- !!!
input=/WEB-INF/jsp/logon/logon.jsp
forward name=success path=/index.jsp/
/action
LogonAction.java:
ActionErrors errors = new ActionErrors();
errors = form.validate(mapping, request);
// Report any errors we have discovered back to the original form
if (!errors.isEmpty())
{
saveErrors(request, errors);
return new ActionForward(mapping.getInput());
}

How do i have 3 actions here?

Hi,
I've got a bizarre problem regarding form validation. A
simple form
is
validated, and when failing this validation I get a blank
html page with
the following source: htmlbody/body/html
The last message in the log is:
Validation failed, returning to '/upload.jsp'
I've read in another thread that somone else experienced the same
thing.
The solution in this case was to use a different
commons-validation.jar.
I'm using exactly the same jars as the validation example
application.
Still with the same result.
Why am I not receiving the original form, like in the validation
example?
I've included the following files for review:
- upload.jsp // The file containing the html.
- web.xml
- struts-config.xml
- validation.xml
- UploadBean.java
Any help would be greatly appreciated!
Kind regards

RE : RE : Validation failes and returns (almost) empty page.
yes but in my case when the validation failed I always get a blank page.
the actionErrors was not sent and the page was not displayed.
I don't understand why the page was not displayed even if the
actionErrors was not forwarded.

Forward retains your request arguments(i.e., actionErrors),
while an absolute url submits an entirely new request(i.e.,
