Distribucija komponenti - problem sa Button komponentom

[stanislav.simunec]

Imam seldeci problem:

Razvili nekoliko as3 class-a, koje se oslanjaju na Yahoo Astra flash biblioteku.
Zatim smo kreirali komponentu (symbol) koja nasleduje jednu od tih naših klasa.
Odlucili smo da distribuiramo tu našu komponentu u obliku mpx ekstenzije. Znaci
eksportovali smo komponentu u swc file i napravili ekstenziju.

Ukoliko zatim upotrebimo komponentu u novom projektu, dobijamo sledeci exception:

TypeError: Error #2007: Parameter child must be non-null.

Ovo se ne dešava ukoliko u novom projektu uz naš menuBar na isti ekran dodamo Button kontrolu (onu koja se nalazi
u standardnom setu komponenti).
Da li je moguce resiti ovaj problem , tako da eventualni korisnici nase biblioteke ne moraju da
dodaju Button komponentu uz nas menuBar ?distribucija komponenti - problem sa Button komponentom
