Re: Indexed list validation

[Matt Bathje]

this is probably a constantly discussed topic and I have 
surely found a load
of inromation concerning this,but it still did not solve my problem.

I have a web page which displays multiple records, each 
record representing
one person. I am using index to retrieve each record.

The person is represented by bean Person:
public class Person {
        .
        .
        private int monthlySalary;
        public int getMonthlySalary() {
                return monthlySalary;
        }
        public void setMonthlySalary(int monthlySalary) {
                this.monthlySalary = monthlySalary;
        }
        .
        .
}
I use this form for the action called:
public final class PersonalForm extends ValidatorForm{
        .
        .
        private List persons;
        public Person getPersons(int index) {
                return (Person)persons.get(index);
        }
        public void setPersons(int index, Person value) {
                persons.set(index, value);
        }
        .
        .
}
and in the JSP, it looks like this:
<logic:iterate id="person" name="personalForm" property="persons"
indexId="index">
        .
        .
<html:text name="personalForm"
property='<%="persons["+index+"].monthlySalary"%>'
styleClass="monthlySalary"/>
        .
        .
</logic:iterate>
Everything works just fine. What doesn't work is the validation.
I have validation.xml looking like this:
<form name="personalForm">
                        <field property="monthlySalary"
                                        indexedListProperty="persons"
                                        depends="integer">
                        <arg0        key="errors.integer"/>
                        </field>
</form>
When the page is loaded, i get the following exception in Tomcat:
ERROR: in validateField
java.lang.NoSuchMethodException: Unknown property 'monthlySalary'
       at
org.apache.commons.beanutils.PropertyUtils.getSimpleProperty(Property
Utils.java:1175)
       at
org.apache.commons.beanutils.PropertyUtils.getNestedProperty(Property
Utils.java:772)
        .
        .
Where am I making mistake?
Thanks for suggetions.
Radek -
I usually do this with Dyan Forms based on Arrays, so the information 
may not be exactly what you're looking for...but based on my experience, 
I would try the following changes:

- change the id field in your iterate to be id="persons"
- change your html:text to be: <html:text indexed="true" name="persons" 
property="monthlySalary" styleClass="monthlySalary" />
- you don't have the code/config for your action here, but make sure 
that it extends one of the validating action form types.
