[CS3 | JS] Can't modify geometricBounds of object

Question

Okay, I've built some very complex scripts in VB but I'm now working on my Thesis on a Mac and trying to script in JS and some things I probably shouldn't be having problems with, I am.
Like this one: I can't modify (or even read) the geometricBounds of a placed graphic. Here are the lines that are applicable:
var myGraphic = myPage.place(File(myFileList[myKeyFile]),[0,0]);
var myBounds = myGraphic.geometricBounds;  (this gives me an error of Undefined)
When I use the Extendscript toolkit's Data Browser to twirl down myGraphic when at a breakpoint on the second line, it says myGraphic = [object PDF] and has attributes of concat(), Array(), hasOwnProperty(), and many others, none of which seem to be attributes of graphics. Nothing familiar.
What am I doing wrong?

Answer 1

Placed graphics are arrays. So after
var myGraphic = myPage.place(File(myFileList[myKeyFile]),[0,0]);
you have a one-element array myGraphic. The graphic itself is myGraphic[0]
To set the geometric bounds, you need to address the graphic's containing rectangle, in other words, its parent:
var myBounds = myGraphic[0].parent.geometricBounds;
