Hi all,

I am using code from a post in Jan, by Wong who outlined code to use to do
a transformation programmatically. The problem is when I go to save the
model created from the transformation, I get an exception suggestion that
the workspace is closed.

Below is the error and then the code (commented where exception occours)

Anybody have any ideas?
Mark
