Using length of items array for a boolean

[Handycam 0 Likes (Newbie)]

I have a button I was trying to enable only if there are items in the transform manager:

 

But it is not enabling when I add items to the transform manager. Am I missing something?

Frankly, I'm not a big Flex guy but this sure seems like a data binding issue that's Flex-related, not so much TransformManager-related. You could just set up a listener for the SELECTION_CHANGE event and have it affect your button's enabled state.

I wound up adding a function call whenever I add or remove an item to update the boolean.

 

I think all I'd need, though, is to make the "items" variable bindable. I can try it out; where is this variable set in your code?
