Type Coercion failed: cannot convert 1 to Array.

Hi,

I've a simple Tween:

TweenMax.to(this, 1, {alpha:.2, repeat:1});

 

I get this error:

 

TypeError: Error #1034: Type Coercion failed: cannot convert 1 to Array.

TweenMax.to(this, 1, {alpha:.2, repeat:[1]});

works though.

 

Perhaps I am being silly, but I think repeat:1 is the correct way to specify repeat. 

 

Cheers,
Andy.

Nope, you're not being silly - repeat:1 is the correct way. I'm not able to reproduce that issue - can you please post a very simple FLA that demonstrates the problem? And what version of TweenMax are you using? I'd definitely recommend using the latest one.

I BET this relates to these hacks I had to introduce because of Air to IOS compilation 'pain in the assness': http://forums.greensock.com/topic/6664-multiple-errors-in-flash-builder-47/

 

I'll have a quick look to see if errors arise near my hacks and report back.

cheers,

Andy.

 

PS Just downloaded Tween* the other day in reponse to IOS silliness.

yep (in tweenLite). Error at that long If statement

 

 

protected function _initProps(target:Object, propLookup:Object, siblings:Array, overwrittenProps:Object):Boolean {

            var p:String, i:int, initPlugins:Boolean, plugin:Object, a:Array;

            if (target == null) {

                return false;

            }

            for (p in vars) {

                if (p in _reservedProps) {

                    a = vars[p]

                    if (p === "onStartParams" || p === "onUpdateParams" || p === "onCompleteParams" || p === "onReverseCompleteParams" || p === "onRepeatParams") if (a) {

                        i = a.length;

[andytwoods]

and this is how I should have done it:

 

for (p in vars) {
				if (p in _reservedProps) {
					if (p === "onStartParams" || p === "onUpdateParams" || p === "onCompleteParams" || p === "onReverseCompleteParams" || p === "onRepeatParams"){
						a = vars[p]
						if (a) {
							i = a.length;
							while (--i > -1) {
								if (a[i] === "{self}") {
									a = vars[p] = a.concat(); //copy the array in case the user referenced the same array in multiple tweens/timelines (each {self} should be unique)
									a[i] = this;
								}
							}
						}
					}
					

 

 

My bad after all.  Sorry bout that. 

cheers,
Andy.
