ajax validation problem in IE8
Struts 2.1.6
I have a form that uses ajax validation before a non-ajax POST. In IE8,
if the ajax validation call returns a field error (like a missing
field), I get the error in a pop up box in IE8: "An exception occurred:
Error. Error message: Invalid argument."
Only happens when there are field errors. If there are no errors, all
is good.
Any ideas?
<sx:submit formId="loginform" ajaxAfterValidation="false"
validate="true" value="sub ajax"
type="image" src="%{imageServer}/continue_arrow.jpg"
id="cont3" name="cont3" />

Some more info: The generated HTML is below.
validation.js (in the css_xhtml theme) uses this line to find the
element before which to insert the new error div.
var firstCtrNode = findWWCtrlNode(enclosingDiv); // either
wwctrl_ or wwlbl_
That function looks for a child div or span whose class matches "wwlbl"
or "wwctrl", or failing that the first span. The generated HTML has
none of those, so firstCtrNode is undefined. Later in validation.js is
enclosingDiv.insertBefore(errorDiv, firstCtrNode);
When the last argument is undefined, FireFox simply inserts the errorDiv
at the end of the enclosingDiv, where IE8 complains.
So what's broken? I've patched the .js file like this for now, but is
that the best solution? Seems like since the code is written that way
that the templates should be generating a div or span that can be found.
My patch:
var firstCtrNode = findWWCtrlNode(enclosingDiv); // either
wwctrl_ or wwlbl_
if (! firstCtrNode) {
// if we didn't find a node to insert before, use the first
child node
firstCtrNode = enclosingDiv.firstChild;
// if still didn't find one, simply do an alert and return
// otherwise IE8 will complain - this should never happen
if (! firstCtrNode) {
alert(e);
return;
}
}
My generated HTML:
<div id="wwgrp_loginform_address1" class="wwgrp">
<div id="wwctrl_loginform_address1" class="wwctrl">
<input type="text" name="address1" size="40" value=""
id="loginform_address1"/></div> </div>

What in the name of Bumba's porcelain alter are you talking about?
Unless IE8 runs RhinoScript I don't see how that's going to help
diagnose a browser-specific issue. Could you explain further?

I'll give that a try. I thought I remembered seeing instructions for a
way to extract those .js files to somewhere so that I can put in some
debugging statements. Do you know about that?
