Re: Error creating a List

[Akiko Ogawa - RS/GIS lab]

Thank you Mr. Riolo,

I solved the problem.
I realized the problem was happening in a different function which used 
atOffset:. I was believing the problem is in the line, "aList = [List create: 
self]" because the error occurred only when I uncommented that particular line.

Thank you again.
