Flex DataBinding Drilling Down Through Arrays

Question

The help page on the BindUtils.bindProperty function:

http://livedocs.adobe.com/flex/3/langref/mx/binding/utils/BindingUtils.html

Has this to say:

"For example, to bind the property host.a.b.c, call the method as: bindProperty(host, ["a","b","c"], ...)."

But what if I need to bind to host.a.b[2].c? How do I do that?

Answer 1

There are often binding issues when you drill down into objects, at least under most normal binding sitautions.

Not sure if this is what you're after, but:

[Bindable] public var myObject = a.b[2]; 

And later in your code:

<myComp myValue="{myObject.c}" />

However, I would consider it highly unusual to bind to a specific element of an array. If you could expand on what you're trying to do; maybe we can point you in a different direction.

Answer 2

It turns out, flex lets me do this: bindProperty(host, ["a","b","2","c"], ...);

Hazzah!
