[T4]: EventListener autoSubmit
Hi,
I've just finally gotten back around to messing with the T4 async stuff.
The first thing I wanted to try was a simple shipping/billing info wizard
where clicking a checkbox labeled "same shipping info" would grab the
shipping info and populate the form on the billing info page.
Generally I have it working. I can update everything asynchronously, which
is awesome. The problem I have is getting the checkbox state. If I use
"elements", the server-side value isn't updated and it appears I can't get
the actual checkbox value from the BrowserEvent. If I use "targets", the
server-side value is updated, but I can't suppress the form submission. I
have something like the following:
@EventListener(targets="sameShippingInfo", events="onchange",
autoSubmit=false)
public void copyShippingInfo(final IRequestCycle cycle, final BrowserEvent
event)
{
...
}
It seems to me that setting autoSubmit to false should not submit the form,
but it is anyway. Even if this were working, would that mean that the
server-side value that the checkbox is bound to would not be updated?
Thanks,
Kevin

Thinking the matter over a little bit more, there's a fairly straightforward
workaround. By removing any listener from the form and binding them all to
submit button action values, I can get the desired behavior. Of course,
this does mean more template changing which is not as transparent as I'd
like, but not terrible either.
The "autoSubmit" parameter seems broken though, so I'll be poking around
JIRA for that.

Ahh. Cool. I guess ideally I'd be able to a serialized copy of the DOM
node, sorta like I can do with jQuery. Then I could dump the server-side
value altogether and just use a plain ol' checkbox.
I guess I'll put EventListener back on the shelf until then.
Thanks for the info,
Kevin

Heh...If it were correctly not submitting the form I'm still not sure
if you'd be able to figure out what the value bound to the checkbox
is.
Marcus did add something semi - recently that may actually give you
what you want. If your BrowserEvent object has a
getMethodArguments() method then you may be in luck. (maybe, don't get
too excited until you try it)
In theory it will take all the arguments to the client side function
(including the javascript event, which should have a
target/relatedTarget/etc attribute attached to it) and serialize them
in some form that you can then try to interact with in the form of a
JSONArray. I've not used it though so don't know what will happen
under which circumstances / etc..
