Yes, as allandt suggests, you should provide a default value for
constructor param
Unfortunately, it's not the only problem with components (at least in CS3)
For me, the worst one is about [Inspectable] parameters (and their setters).
As described here
http://www.bit-101.com/blog/?p=1181
setters are called lo-o-ong AFTER constructor
And, even if I set my init() as listener for ADDED_TO_STAGE event... setters
are not called before it :-(
Any advice to determine the exact time setters are called?
