"cachedOrphan" with greensock on Gaia

Has anyone ever gone through an error like this one:

Code:

---

ReferenceError: Error #1069: Propriedade cachedOrphan não encontrada em com.greensock.TweenLite e não há valor padrão.
at com.greensock::TimelineLite/addChild()
at com.greensock::TimelineLite/insert()......etc

---

"property cachedOrphan not found in com.greensock.TweenLite..."

??
I get that error while testing a movie (made with/Gaia Framework) on Flash IDE.

please help! thanks!
