First, scratch my hypothesis about problems occurring within the
class itself.
To answer your question, a mouse event (MOUSE_UP) on the particular
LiquidObject prompts it to access its siblings.

As I understand, each child attempts to access their siblings via the
parent. What triggers the children to access their siblings?

Thanks for this reference. I performed a simple test and it works.
However, for my particular example, I receive an error.
var liquidObject:LiquidObject = parent.getChildAt(i) as LiquidObject;
assigns null to liquidObject.
The only thing that has worked for me so far is:
if (parent.getChildAt(i) is LiquidObject) {
trace(LiquidObject(parent.getChildAt(i)));
}
My only explanation is that I'm attempting to perform this cast
WITHIN the LiquidObject class itself.
I currently have the stated workaround, but any further insights
would be of interest to me.
Best,
Paul
