This may or may not be a bug. However, when using the following code with ".from" the sequencing breaks (everything happens at once and myTimeline.stop() doesn't work...
import com.greensock.*;
//create the timeline
var myTimeline:TimelineLite = new TimelineLite();
myTimeline.insert(new TweenLite.from(square1, .5, {_x:-50}), 0);
myTimeline.insert(new TweenLite.from(square2, .5, {_x:-50}), 2);
myTimeline.insert(new TweenLite.from(square3, .5, {_x:-50}), 4);
//stop the timeline
myTimeline.stop();
However, using runBackwards:true works, but the objects properties aren't set until the delay time is reached ...
import com.greensock.*;
//create the timeline
var myTimeline:TimelineLite = new TimelineLite();
myTimeline.insert(new TweenLite(square1, .5, {_x:-50, runBackwards:true}), 0);
myTimeline.insert(new TweenLite(square2, .5, {_x:-50, runBackwards:true}), 2);
myTimeline.insert(new TweenLite(square3, .5, {_x:-50, runBackwards:true}), 4);
//stop the timeline
//myTimeline.stop();
Again, not sure if that's a bug or I'm just misunderstanding how to and from work.
THanks again
