Can anyone (Ben?) provide an example of how I can prepopulate an MVCArray? I think that's my problem.
Ben, the example you provide instantiates an empty array and fill it on click. I'm doing that in my script, but it must also pre-load some stored polygons. I'm trying to get away from the way we used to do it in v2 with a thousand lines of pushing points. If I could construct the array of points and define it in the constructor that'd be much better, to my eyes anyway. I've tested and can manually push (.setAt) points into the path/poly but any time I've tried to pre-define it I get the constructor errors I've mentioned.

I keep getting errors like this: "Invalid value > for constructor parameter 0: [object > Object]http://maps.gstatic.com/intl/en_us/mapfiles/api-3/22a/main.jsLine > 52".
