Iterator: field errors.

[Satheesh Kannan A B <sa...@hcl.com>]

Hi,

I have a requirement like, am iterating a list of values and populating in a text box. It may be more than 5 rows. I need to validate whether it's an integer and want to display error message below the field. For a normal field with a unique I have done it well. But I don't know how to do for list if validation fails. Since after validation fails the iterator grid also empty and am not able to display field values.
<s:iterator values="objectList">
<s:textfield name="bo.name" />
<s:fielderror name="bo.name" ></s:fielderror>
</s:iterator>
Please suggest me how to populate grid values in jsp if validation fails and also validation messages below field of each row.



Thanks  and Regards,

Satheesh Kannan A B

I think, you need separate the field names by list index -- since your
data model is a list--,
to indicate which [textfield] should be captured by which POJO element.





And also, you need separate the field name of validation error, to
indicate POJO element it belongs.

So, i think code should likes:

JSP:
<s:iterator values="myList" status="rowStatus">
  <s:textfield name="myList[#rowStatus.index].name" />
  <s:fielderror name="myList[#rowStatus.index].name" />
</s:iterator>

Validation:
addFieldError("myList[index].name",getText("error.code"));

Hi,
Generic I have given a pojo class List<PojoClassBO> and am doing validation as a separate method in my action as given below.
 List<PojoClassBO> boList = new ArrayList< PojoClassBO >();

Public String save(){

        If(isValid())
        {
                Continue....
        }else{
Return "input";
}

Return "success";
}

Private Boolean isValid(){
        if(String.isEmpty()){
                addFieldError("bo.FieldName",getText("error.code"));
        }

        if (getFieldErrors().size() > 0) {
                        return true;
        } else{
                Return false;
        }
}



Thanks  and Regards,

What is the data type of objectList?

How did you execute the validation, and how did you add the field error?
