Retrieving a Attribute from an Object Using an Expression in a Workflow

Hi All,

I need to retrieve an attribute ("Operation") which which I have added to a Change Notice in a workflow expression - since the value of this attribute alters downstream activities.

So far I have got as far as:

wt.change2.WTChangeOrder2 co = (wt.change2.WTChangeOrder2)primaryBusinessObject;

String coOperation = ...

Also by using the above code, does it matter that I want to retrieve the attribute from a soft type of the change notice.

Any help would be great.
