Problem with Struts2 validation

Hello All,

I have a registration page known as student registration.

there are few autocompleter fields like country dropdown, state drop down etc.

I am using struts2 validator to validate that none of the fields should be blank. If any field is blank it comes back to same page and displays the message in red that the particular field is required.

now the problem is when it comes back on same page incase of blank field the dropdowns are not working. Autocompleter is not generating the list.

Not sure how to help without any code, configuration, or anything.

Registration page

<%@taglib prefix="apt" uri="/struts-tags" %>
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>Student Registration</title>
         <apt:head theme="ajax" />
    </head>
    <body>
        <table>
             <apt:form action="insertStudentRegistration">
                 <a >Click to Upload</a>

My validate xml looks like

and action xml is

The validation is working fine. If it finds any blank field it goes back to registration page and displays the message. But this time autocompleter does not populate.

Hello All,

I rectified the problem myself.

Thanks to all.

It's nice to include the solution so that when future searchers have a similar problem they're able to also see some solutions.

A couple of notes:

- Why do you use the "apt" prefix for the S2 tags?
- Why don't you use the framework's default result names (lower case)?

Using non-conventional/non-default naming conventions is fine, of course, but make the code more difficult for new developers to deal with.
