Mark Reynolds commented on TAPESTRY-1062:
-----------------------------------------

Never mind. So sorry. My bad.

I have extended the validation delegate to change the decoration of invalid 
fields. I surround the label/input pair with a single div by writing the open 
<div> in IValidationDelegate.writeLabelPrefix() and the closing </div> in 
IValidationDelegate.writeSuffix(). Obviously, this won't work with 
@EventListener as it handles each element separately.

>          Issue Type: Bug
>          Components: Core
>    Affects Versions: 4.1.1
>         Environment: Tapestry 4.1.1-20060813.221855-15

> I have an @EventListener method listing to a PropertySelection named "course" 
> which updates another PropertySelection named "section":
>     @EventListener(events = "onchange", elements = "course", submitForm = 
> "importForm")
>     public void courseSelected(IRequestCycle cycle, BrowserEvent event) {
>         cycle.getResponseBuilder().updateComponent("section");
>     }
> This results in a warning in the browser: "WARNING: 1:20:20 PM: No 
> ajax-response elements recieved."
> After poking around with Venkman, I found that the response xml looks like 
> this:
> <ajax-response>
>   <response id="importFormhidden" type="element">
>     <div style="display:none;" id="importFormhidden">
>       <input type="hidden" name="formids" value="course,section,import"/>
>       <input type="hidden" name="submitmode" value=""/>
>       <input type="hidden" name="submitname" value=""/>
>     </div>
>   </response>
>   <response id="section" type="element">
>     <select name="section" id="section">
>       <option value="0" selected="selected"></option>
>       <option value="1">101-001</option>
>     </select>
>    </div>
>   </response>
> </ajax-response>
> Notice the unmatched </div> on the third to last line which causes a parsing 
> error in the response.
