RE: [flexcoders] Re: Another data binding question - on class 'XML' (class is not an IEventDispa
Ok, in my case, the problem was solved by casting (or top level function
conversion, or whatever it really is). In the repeater, this produced
the warnings:
myProperty'[EMAIL PROTECTED]'
This should have been expected, since currentItem is type Object, and we
know better than to bind to that. The fact that the compiler recognized
and reported the correct contained class as 'XML' led me astray. This
corrects the warnings:
myProperty'{XML(myRepeater.currentItem)[EMAIL PROTECTED]'
And a related note, the XML class does definitely dispatch the events to
support binding. My search of the documents however did not turn up any
definitive statement to that effect. In fact, there are contradictory
statements. If I have time I will continue to investigate the docs.
I have posted my XMLBinding proof app on cflex if anyone cares.

I don't think that is correct. The XML class does dispatch the events
necessary for binding. I'll look for the doc reference in a bit.

It may be working so far because the objects you set your XML as a
dataProvider are wrapping it as an XMLListCollection or similar, which
will provide notification mechanisms. The XML class as-is can't
participate in binding as it doesn't dispatch events (which is required
for binding).

All,
I was troubleshooting this binding warning the other day myself and ran
across this blog - that at least in my case - addressed the issue,
complete with a detailed explanation and code examples. The key is
using an ObjectProxy.

Hey, Julien, did you figure this out yet? I just noticed it in my
trace
log. And oddly, I do not get the warnings in FlexBuilder.
Perhaps it is a spurious warning? The archives don't show any
definitive
solution. I'm still looking.

Subject: [flexcoders] Another data binding question
Hi list,
I have a DataGrid in my application that gets populated from an XML
file. Displaying the data in the grid 'as text' works fine, but I
wanted to use an item renderer, as soon as I do this I get this
warning
:
warning: unable to bind to property 'icon' on class 'XML' (class is
not an IEventDispatcher)
How can I get rid of that warning? Do I have to cast the XML to some
other class, and how could I do this?
Thanks for your help.

Re: [flexcoders] Re: Another data binding question - on class 'XML' (class is not an IEventDispa
Interesting... I'd be curious how the curly-brace syntax translates to AS3.
There are watchers for XML in the mx.binding.* package. Perhaps they are
automatically used? They work by basically injecting some stuff into the XML
object's prototype... which is a cool way to retrofit a built-in class! ;-)
It'd be great to see some more detailed explanation of this from Adobe... at
the very least, some commitment to intended behavior that we can depend on
(as opposed to this being some kind of happenstance side-effect). It would
be very handy to have a nice fat XML document that I could modify at will
and have various bindings update auto-magically.
