Subject [jira] Created: (WW-2585) AJAX validation does not work with sx:xxx dojo tags (javascript error)

AJAX validation does not work with sx:xxx dojo tags (javascript error)
----------------------------------------------------------------------

                 Key: WW-2585
                 URL: https://issues.apache.org/struts/browse/WW-2585
             Project: Struts 2
          Issue Type: Bug
          Components: Plugin - Dojo Tags
    Affects Versions: 2.1.0
         Environment: struts2-dojo-plugin-2.1.0.jar struts2-core-2.1.0.jar xwork-2.1.0.jar

            Reporter: Vladimir Limansky


JSON data returned from the server can not be inserted correctly into the page content.

Let's examine the following code in validation.js (struts2-core-2.1.0.jar)

function addErrorXHTML(e, errorText) {
    try {
        // clear out any rows with an "errorFor" of e.id
        var row = e.parentNode.parentNode;
........
In case of 'normal' non-dojo field being validated (for instance s:textfield), the first parameter
that is passed to this method (e) is <input type=text > so that for

<tr>
     <td>
            <input type="text" id="passed_field">
     </td>
</tr>

So e.parentNode.parentNode returns <tr> element so that we can insert error message
just before it.
________________________________________________________________________________
Consider the same situation with (for instance sx:datetimepicker) tag. The content we have
is as follows:
<tr>
     <td>
           <span>
                <input type=hidden/>
                <div ......./>
           <span>
     </td>
</tr>

So e.parentNode.parentNode will return <td> tag instead of expecting <tr> tag.


So this causes 3 problems:
1. Error messages are not cleaned
2. Error message arises in incorrect place
3. method addErrorXHTML shows alert message
