Setting value for a key programmatically for arg0 tag

[Naseem Khan]

Hi,

Can we set programmatically the value corresponding to a key? I have already set resource false for arg0 tag.

<arg0 key="error.defaults.loanPrequal.loanNeed" resource="false"/> 

Now in the error message, for {0}, I want the value which I have set programmatically.

I tried changing the value of arg0 key by variable tag.

Here is the code

<arg0 key="${var:validateCDField}" resource="false" /> 
<arg1 key="loanNeed.purchasehome" />
<var>
  <var-name>validateCDField</var-name> 
  <var-value></var-value>
</var>

public static boolean validateCDField(Object bean, ValidatorAction va,
        Field field, ActionMessages errors, Validator validator,
        HttpServletRequest request) {
 
String fieldValue = ValidatorUtils.getValueAsString(bean, field.getProperty());
Arg [] args = field.getArgs(va.getName());        
  for(int i=0; i<args.length;i++){
    String key = args[i].getKey(); 
    if(key.equals(field.getArg(0).getKey())){
       continue;
    }   
    Var var = field.getVar("validateCDField");
    value = Resources.getMessage(request, args[i].getKey());
    if(fieldValue.equals(value)){ 
        [B]var.setValue(fieldValue);[/B]
        errors.add(field.getArg(0).getKey(), Resources.getActionMessage(validator, request, va, field));
        return false;
     }           
  }  
  return true;
} 

My error message is, We don't provide loans for {0}. Here this 0 points to arg0 whose value is the value of variable validateCDField which I am assigning by our validate method.

Still I am not getting the value at place {0}

Can anyone please help me?

Is there anyway to map arg key with user entered value of form field?

<field property="loanNeed" depends="validateCDField">
<arg0 key="${this:value}" resource="false"/>

Just like ${var:varName} dynamically maps the value of var with key, similarly I tried with ${this:value}, but its not working. In place of form field value, I am getting ${this:value} as it is.

Please help

Hi, I solved it by ...

field.getArg(0).setKey(fieldValue);

here fieldValue is user entered value
