xml validation with indexed properties.
I'm using struts and got issue with their xml validation framework. I have form with some indexed properties where element is just plain String. And I need make validation for it. I tried to use indexedListProperty for this case, but it doesn't work and as I read in 'Struts in Action' it works only for indexed properties with nested properties(i.e. indexedProperty[].nested) and it's not suits for my issue. Maybe anyone knows how to resolve this?
Re: Validation of indexed properties
Hi Cielpa,
'Invalid property' would suggest that your form does not contain the
property searchList. It is difficult to tell without a bit of background and
seeing some code. Can you explain what you are doing and show me your
struts-config.xml file.
By the way, your form should be declared as a DynaValidatorForm. There is no
such thing as a DynaValidatorActionForm.
For example..
form-bean name=myForm type=org.apache.struts.action.DynaValidatorForm
form-property name=searchList type=java.util.ArrayList/
/form-bean

Hey,
I have a similar problem with DynaValidatorActionForm.
It says that invalid property when i have a ArrayList in the

form-bean declaration.
Any idea?
Thanks and your help is appreciated.

I get the following error message when I try to access an ArrayList of

root cause
java.lang.IndexOutOfBoundsException: Index: 1, Size: 0
java.util.ArrayList.RangeCheck(Unknown Source)
java.util.ArrayList.get(Unknown Source)
org.apache.struts.action.DynaActionForm.get(DynaActionForm.java:298)
Here is some background to the problem...
In my session I have an ArrayList called studentsList of objects of type
experiment.mybeans.Student. A Student object has getter and setter
methods for id, year and gradeAverage.
In my students.jsp I create a table by iterating through my student
objects like this...
c:forEach var=students items=${sessionScope.group.studentsList}
trtdhtml:text indexed=true name=students property=id//td
tdhtml:text indexed=true name=students property=year//td
tdhtml:text indexed=true name=students
property=gradeAverage//td/tr
/c:forEach
As you can see the table contains empty text boxes and I would like to
validate these have been filled in, so in struts-config.xml I create my
dynavalidatorform as follows...
form-bean name=studentsForm
type=org.apache.struts.validator.DynaValidatorForm
form-property name=students type=java.util.ArrayList /
/form-bean
And in validation.xml I place my validation rules...
form name=studentsForm
field property=id indexedListProperty=students
depends=required
arg0 key=error.studentid.required/
/field
field property=year indexedListProperty=students
depends=required
arg0 key=error.studentyear.required/
/field
field property=gradeAverage indexedListProperty=students
depends=required
arg0 key=error.studentgrade.required/
/field
/form
Now here is where things start to go a bit pear-shaped
I have read somewhere online that I need to populate the form ArrayList
before I get to my jsp page. So I have created an action class called
PreStudentsAction.java which takes the student ArrayList out of the
session and assigns it to the student ArrayList in the form before
forwarding to the students.jsp page...
public class PreStudentsAction extends Action{
public ActionForward execute(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception
{
DynaValidatorForm myForm = (DynaValidatorForm)form;
Group group = (Group)request.getSession().getAttribute(group);
ArrayListStudent students = group.getStudentsList();
myForm.set(students, students);
return (mapping.findForward(success));
}
}
Finally when I run my application my table is displayed but when I fill
in the table and press submit I get the IndexOutOfBounds error. It
appears to me that the student ArrayList in the form remains empty and
that my Action class was unsuccessful in populating the form's ArrayList.
Can anybody see what I'm doing wrong?

Re: Validation of indexed properties
Sorry Cielpa, my mistake.
Turns out there is such a thing as a DynaValidatorActionForm. Shows how much
I know.

Re: JavaScript Validation of Indexed Properties
No Struts does not do javascript validation of indexed properties.
The createDynamicJavascript() method in JavascriptValidatorTag has the
following code:
// Skip indexed fields for now until there is a good way to handle
// error messages (and the length of the list (could retrieve from
scope?))
if (field.isIndexed()
|| field.getPage() != page
|| !field.isDependency(va.getName())) {
continue;
}
If you're interested in working on a patch, that looks like the place to
start.

Does Struts JavaScript validation work with indexed properties? If so,
a pointer to an example would be appreciated. If not, confirmation that
it's not supported would be appreciated.
