Say I have a variable counting up to 10 and back down to 1. It does this in a loop, just going from 1 to 10 back down to 1 back up to 10..
The variable is bindable. Let's call it COUNT. I have a Label that has COUNT as its data source, so the label's text value goes from 1 up to 10 and back down again. Now, let's say I have a button that I want to enable whenever the variable is equal to 5. There is a little more logic around this behavior and so I don't think it's a flat out dataprovider solution. What I think I'd like to do is add my own event listener to COUNT and it would do the logic of checking to see if COUNT's new value == 5 and if so, enabling the button. But most of that observer/observable interface seems hidden to me via the [Bindable] construct. Then my method could do whatever additional logic I can dream of. Is there a way to add my own listener methods to [Bindable] variables? Or is there another standard way of addressing these issues within the Flex paradigm? Thanks much - cris.
