T4.1:Event connect strangness
Hello List,
I have a form with a @PropertySelection component in it, when this changes some elements on the page change. The HTML looks like this:
<form jwcid="taskSelection@Form" style="display: inline;" updateComponents="ognl:{'allDetails'}">
<select jwcid="taskSelect@PropertySelection" value="ognl:taskList.selection" model="ognl:taskList" style="width:250px;"></select>
</form>
This is being listed to by a method like this:
@EventListener(events = "onchange", targets = "taskSelect", submitForm = "taskSelection", async=true)
public void taskSelectListener(IRequestCycle cycle)
{
}
Now I also want the user to be notified that the application is doing something so I have a script file with this code in it to show a loading dialog:
if(dojo.byId('taskSelect')!= null)
{
dojo.event.connect(dojo.byId('taskSelect'),"onchange",function(){
document.body.style.cursor='wait';
dojo.widget.byId("loadingD").show();
});
}
Now this all works fine the first time the select is changed, but after that the loading dialog isn't shown. Is there something that I', doing wrong?
By the way I'm using Tapestry 4.1.6
Thanks,
Craig

Thanks for that. It wasn't included, it is now and all is working.

is the above script included in the ajax response?
Since the form is submitted and the new form markup replaces the old one,
the (new) taskSelect will not be monitored for changes
