Lee Cheng Wei commented on WW-2058:
-----------------------------------

I'm using Struts 2.0.11, IE 7.0.6 and FF 2.0.0.11. The error messages are duplicated each time the form is submitted. Verified that the xhtml template is using the fix (JS). Tried to add alert() to end of the JS function but it doesn't get called. The form is a simple login form with no hidden field. Is this a problem with the browser or Javascript fix?

> The method clearErrorMessages in the xhtml client side validation template (template/xhtml/validation.js) fails in firefox. This results in the error messages being duplicated each time the form is submitted.
> The problem arises from the first three lines of code in the function:
>     var table = form.childNodes[1];
>     if( typeof table == "undefined" ) {
>         table = form.childNodes[0];
>     }
> This presumes that the first (or second) node of the form element is the field table. However in firefox hidden fields within a form are moved in the DOM to the top of its children. Thus wherever you put the hidden elements in the form they appear in the DOM at the top. The same problem does not occur in internet explorer or if no hidden fields are present. I have not tried other browsers.
> I have replaced these three lines with the patch:
> // get field table
> var table;
> for (var i = 0; i < form.childNodes.length; i++){
>     if (form.childNodes[i].tagName != null && form.childNodes[i].tagName.toLowerCase() == "table"){
>         table = form.childNodes[i];
>         break;
>     }
> }
> if (table == null){
>     return;
> }
> This solves the problem.
