Jesse:
I modified the demo to use @Any components with radio buttons in the
AjaxSubmitExample page (such as the functionality originally intended).
Now I left the demo broken, but it's not exactly the case with Tapestry
radio buttons. If you see closely, I'm using @Any to create the radio
buttons (the Tapestry radio buttons have other functions).
So, the question is, can I connect an @Any component to an
@AjaxFieldObserver? Dojo sure can, through event.connect(), and the
requisites are there: the component unique id, and the submit function.
The only thing missing is the link. eventListener doesn't work because
it appears to be only for form components.
I think maybe "FieldObserver" doesn't reflect the true meaning of this
component. This is not a component on form elements, this is a *form
submit* component (maybe AjaxSubmitEvent or something like that is more
appropiate). So, I think users should be able to submit their AjaxForm
in any way they can, without needing specific form components to do so.
Don't you think??
Now, I have 2 approaches to connect these kinds of component:
1) Extend eventListener to accept non-form components. Is this actually
possible? I don't understand - yet - the logic behind these render
contributions, so I think you can give me some light in this respect.
2) Implement a binding component that's just a wrapper for
dojo.event.connect(). Such as this:
<span jwcid="@AjaxConnect" component="component.someRadio"
event="onclick" listener="component.someAjaxEvent" />
This would also do the trick. Of course it doesn't solve the Tapestry
radio button issue, but it sure allows people to connect arbitrary
elements to a submit event. Who knows? Maybe someone wants to submit
their form in an image rollover!
(By the way, I also fixed a small bug in AjaxFieldObserver - now it's
not taking form focus. ;)).
This FieldObserver is the only blocker, IMO, to the beta-1 release.
