Re: What Changed With ESRI Layers?

Hi Karl,

There was a bit of type checking added to the esri plugin package. I
think it also assumes that graphics inside the top-level list are
themselves in a sub-list. That will change in the future.

Also, the lists do need to be modified to complain if something is being
added to them incorrectly.

Sorry about the troubles, but I'd be interested in hearing more about
them, especially if you find out there is something wrong in the code.
