Using DynaValidatorForm 2007-01-18 - By bjorn.de.bakker@(protected)
Back
Is this deprecated ? The reason why I'm asking is that I want to use it in my
application, but I can't seem to find a lot of articles on it. The guide on
the Struts website is well written, but beside that, not a lot of people have
written tutorials on it.
I have some problems with the ActionErrors. When I submit the form, the
Validator validates the form and returns an error if one of the checks doesn't
pass. The problem is that you have to add something to the ActionErrors-object
, but that seems to fail.
This is how I work:
- I create the form in my struts-config file, type org.apache.struts.validator
.DynaValidatorForm.
- In validation.xml, I add the fields whom need to be checked
- In validator-rules.xml, I add a definition, with methodParameters = Object,
ValidatorAction, Field, ActionErrors, HttpServletRequest.
- In my Java-class I define the method and when a check fails, this happens:
actionErrors.add(field.getKey(), Resources.getActionMessage(req,
validatorAction, field));
If I google it, the tutorials I find state that it should be Resources
.getActionError. But according to the 1.3.5-reference, getActionError doesn't
exist and you need to use getActionMessage. But when I use this code, I get
this message:
[http-8080 (See http://ttp-8080.ora-code.com)-Processor24] ERROR org.apache.commons.validator.ValidatorAction  -
Unhandled exception thrown during validation: null
java.lang.NullPointerException
Can somebody help me plz? Pretty annoying and I can't find what's causing this
problem :-/.
