I don't see how there is any scoping issue as any component that receives a
property/style of type Function calls that function without any specific
scope as in:
<MyComponent formatter="myCustomFormatter" />
class MyComponent {
var formatter:Function;
function doSomething() {
var whatever = formatter(data);
}
}
Best regards,
