Hi everyone,
I saw in the documentation that one can't bind to elements of an arrays.
Indeed, it seems that something like <label text={someArray[1]}/> does nothing.
I searched through the mailing list archive and made some tests myself, but couldn't find
something really simple.
- The first step seems to put :
"someArray.replaceItemAt(1, item)" instead of "someArray[1] = item"
The reason is that it will make someArray dispatch a "modelChanged" event.
- I tried several things, including using mx:Model or mx:Binding tags to make the linkage,
but then I doesn't work, and I couldn't find anyhting better than :
"someArray.addEventListener("modelChanged", this);"
With an event handling function that does the binding.
Although it is working, it looks a bit dirty. I hope there is some way to do it without any actionscript lines,
just like the other bindings.
- Here is a little example of something that I took as a starting example. What can be done to make it work ?
<mx:Script>
<![CDATA[
var sourceArray = [ "one", "two", "three" ];
]]>
</mx:Script>
<mx:TextInput id="sourceText" text="Replace It ! "/>
<mx:Button label="Update data" click="sourceArray.replaceItemAt(1, sourceText.text);" />
<mx:Label text="sourceArray.getItemAt(1)='{ sourceArray.getItemAt(1) }'" />
Thanks,
Damien __._,_.___
