" if i make a var bindable, i can give values to it later on a function? "
Absolutely. For example, untested:
[Bindable]private var _xmlRData:XML; //bindable instance var containing data
....
private function rLoaded(event:Event) : void{
_xmlRData = XML(event.target.data); //set the instance var value
}
...
<!-- Bind the text property to the xml nodes value -->
<mx:Text id="txtBy" text="{_xmlRData.info.author.name.text()}" .../>

Subject: Re: [flexcoders] asigning text with script error
mmm,
that could explain why the 1st time i exec it on fireworks it works
while the second it doesn't (it might cache some content)...
but i will read an XML depending on values given...so i don't know how
to do it without AS...
i did directly on the components at first, but then it allways
complained that data still not came when component drawn.
about bindable...i don't really know what it does/how to use it...
if i make a var bindable, i can give values to it later on a function?
thnx
