validation for multiple dependency arrays

[Raymond Holguin]

To keep it simple I have 2 fields in my form (First + Last name) user can enter multiple names and both fields are required if they enter multiple names.

So i have my basic setup

ACTION FORM

  

private String[] fname = new String[10];
private String[] lname = new String[10];  

//getters & setters....

JSP

  
<html:text property="fname[0]/>  <html:text property="lname[0]"/>
<html:text property="fname[1]/>  <html:text property="lname[1]"/>
<html:text property="fname[2]/>  <html:text property="lname[2]"/>
....

now what i want to do is make sure that if they type something into fname[2], lname[2] also has a value in it. This is where my problem starts. I am using custom validator methods so in my validation.xml i have something like this

VALIDATION.XML

  
<field property="fname" depends="validateNames">
    <arg0 key="personalInfoForm.fname.name"/>
    <var>
    	<var-name>currentIndex</var-name>
    	<var-value>??????</var-value>
    </var>
</field>

basically what i want to do is when i send the fname property to my validateNames method, i want to know which index i am current validating (fname[0] or fname[1] .....). that way i can check teh correpsonding index in the lname field to see if its NULL or not and validate accordingly. maybe using the <var> tag is not what i want to do and there is a way inside the validating method to pull that index out im not sure.


VALIDATOR

  
public static boolean validateNames(Object bean, ValidatorAction va,
			Field field, ActionMessages errors, HttpServletRequest request) {


//IN HERE CAN I GET THE CURRENT INDEX SOMEHOW??
		
}  

can someone please help me with this??
thanks
