Director 1.4 Turntobook() With Pinchandzoom?

Does anyone have any working sample code using director book interface and pinchtozoom functionality? it seems that the touch events are clashing and I am unable to implement any kind of pinch zoom? GEtting an error in the calculateDelta function when called from the began phase of the touch event…

each of my book page is a full screen image. 

has anyone else faced this before?
