Setting the id like that won't let you reference it later by ID.
Also, you're trying to use the MXML way of assigning event listeners
in AS. Try something like this
private var cp:Array=new Array();
for (i=0;i<5;i++){
ssPicker = new ColorPicker();
cp.push(ssPicker);
//you'll need to look at event.currentTarget to see which picker it
is
ssPicker.addEventListener("open", yourFunction);
}
You may find that you're better off using a data source that a List
control is bound to for this. When the color pickers change the data
source, the descriptBoxes, which would be itemRenderers for some
other list based control, can automatically pick up the change.
