Tap 4.1.1 TextField Ajax question
I am attempting to use @EventListener to submit the value of a TextField
onChange. So, I have an input defined:
<input jwcid="myField" value="ognl:text"
displayName="Text" />
In the page class I have:
@Component(bindings = {"validators=validators:required"})
public abstract TextField getMyField();
@EventListener(events={"onchange"}, elements="myField")
public void testEvent(IRequestCycle cycle)
{
logger.debug("LOOKHERE... " + getText());
}
But I'll be darned if any of the events are firing.
To rule out other problems, I copied the "big brother is watching"
sample from:
http://tapestry.apache.org/tapestry4.1/ajax/eventlistener.html
to the same page, and it works just fine..
30 Apr 2007 11:35:36,658 [http-8080-Processor24] DEBUG
com.starpoint.instihire.web.tapestry.page.Test - User clicked on x/y
coordinates 159/326
Am I barking up the wrong tree? My final goal is to have a dropdown
update it's contents based on the text in the TextField, but until I can
dynamically get it's value I'm stuck.
Thanks in advance for all the help.

I would be very happy to use Tapestry 4.1.2 but I run into a problem
every time I try the latest snapshot:
java.lang.NoClassDefFoundError: ognl/enhance/ExpressionAccessor
I assume this related to the OGNL stability you mention.
Is there a newer beta of OGNL I grab from somewhere to get moving along? If so I'll just throw it in my local repository for now.
Thanks again
Tony

You want to use targets="" . Elements = "" is strictly for pure html
elements and not tapestry components.
If you use the 4.1.2-SNAPSHOT version it will also automatically figure out
which form your targeted components are attached to and submit that as part
of the event so that you can do things like get the current value of the
field.
4.1.2 should be released very soon, just holding out for ognl stability.
