>             Project: Tapestry
>          Issue Type: Bug
>          Components: XHR/dhtml/Ajax
>    Affects Versions: 4.1.2
>         Environment: java 1.5.0_07, osx 10.4.9, tomcat 5.5.24
>            Reporter: Julian Wood
>            Priority: Minor

> It seems that if you update a component inside which there is another component on which there is an EventListener, you will lose that EventListener.
> For example:
> <div jwcid="myTable@Any">
>     <div id="nameHeader">Name<span jwcid="@Insert" value="ognl:sortAscending?' ^':' v'"/></div>
> </div>
>     @InitialValue("ognl:false")
>     @Persist
>     public abstract Boolean getSortAscending();
>     public abstract void setSortAscending(Boolean sortAscending);
>     @EventListener(elements = "nameHeader", events = "onclick", async = true)
>     public void sort(IRequestCycle cycle)
>     {
>         setSortAscending(!getSortAscending());
>         cycle.getResponseBuilder().updateComponent("myTable");
>     }
> So if you load this up in a browser, then click on 'Name v', it changes to 'Name ^' like it should. But if you click it again, it has lost it's EventListener, and 'Name ^' doesn't change. The ajax response didn't include this bit which creates and connects the event:
> tapestry.cleanConnect(dojo.byId("nameHeader"), "onclick", "event1702620775");
> tapestry.event1702620775=function(e){
> var content={beventname:"onclick"};
> tapestry.event.buildEventProperties(e, content);
> if (!content["beventtarget.id"]) content["beventtarget.id"]="nameHeader";
> tapestry.bind("/myapp/app?component=adminBillableItems&page=Admin&service=directevent&session=T", content);
>  };
> dojo.event.connect(dojo.byId("nameHeader"), "onclick", tapestry, "event1702620775");});
