Hi all,=A0

I'm doing some scripting= in AE, and need to iterate through an Array of Objects, so need to find ou= t the number of items in the array in order to set up the loop.

<= br>

I had expected to be able to get the number of items using myArr= ay.length, but this gives an 'undefined' error in ExtendScript.

The array has been populated with a loop in the follo= wing manner:

for (var i=3D0; i < myWidthValues.length; i++)

=

{

myArray[i].width=3DmyWidthValues[i];

myArray[i].= height=3DmyHeightValues[i];

}

(this isn&= #39;t the real code, just a simplified example)

And the array is functioning as expected (so for exampl= e myArray[2].width gives the result I expect).

Is = there a reason that an Array of Objects won't return a 'length'= value?

(I know this question would be better suited to a gener= al javascript forum, but I've trawled internet forums to no avail, and = thought I'd ask here first in case it's a quirk specific to ExtendS= cript).

Any help much appreciated!
