Upgrading From Model-Glue 2

Upgrading from Model-Glue 2 to Model-Glue 3 has been designed to be as painless as possible. Great pains went into ensuring backwards compatibility as much as humanly possible.

The process to upgrade from Model-Glue 2 to Model-Glue 3 should be as easy as replacing your existing ModelGlue directory with a fresh MG3 copy. Sounds easy, doesn't it?

Well, we wish it were. There are a few issues that might trip you up. We'll explain what they are and how to get around them:

1. ColdFusion 9 introduced the trace() method. This conflicts with the MG trace method on EventContext.cfc. You will need to update your codebase and change all instances of trace() to addTraceStatement()

2. Model-Glue 3 requires at least version 1.2 of the ColdSpring Framework (http://www.coldspringframework.org/).
