Ok, next thing to see is if collectionChange events fire when the values
are reset to false.

Subject: [flexcoders] Re: Item Renderer Not Updating

 

I need to correct my previous post with some changes I've made.

I changed the model property to 'isSelected', and am binding that to
the 'selected' property of the CheckBox like so:
<mx:CheckBox id="myCheckBox"
selected="{data.isSelected}"
label="{data.label}"
x="0" y="0"
height="20" width="100%"/>

Now if I set some of the values to true in the command class listed
below, it picks it up. So that is working, but if do the user gesture
that is suppose to reset all values to false, that doesn't happen
(even though the model is set correctly).

Thanks for the help!
