From: Robert Evans Date: 2006-07-07T09:47:51+09:00 Subject: Marshal Problem Hi, I've got a serialized object that I am trying to read back in with Marshal. When it reads the class back in, it complains with the following message: undefined class/module ; This is running on windows. Under Mac OS X, everything works fine (Note: I serialize and de-serialize on the same platform, so it's not a cross platform issue.) Anyone have any clues as to why it is looking to resolve a class called ";" from the serialized file? Thanks, Bob Evans Agitar Software Know Your Code, Trust Your Code
