Just let me check if I have understood you correctly - you want a custom=20
property editor that can convert from a comma separated string to a=20
hash-set of Role objects, and that should be injected using an property=20
expression (excel header) like "user1.roles"?

The way to do this is to write the PropertyEditor you want, and then=20
register it with the JavaBeans standard registry (global):

**java.beans.PropertyEditorManager#**registerEditor(...)

If you use Java 1.5, you can even make it target only HashSet<Role> or=20
if you use Java 1.4 you will have to settle for HashSet.

The best place to put this would be in setupMethod() - a callback in=20
your DDSteps testcase. Then make sure you un-set it in tearDownMethod(),=20
by calling registerEditor(HashSet.class, null). That way it's only used=20
when necessary.

In Spring you can add PropertyEditors to the context xml file, but since=20
DDSteps can be used without Spring, we haven't added that feature yet.=20
I'd be very happy if you filed an enhancement request in our bug tracker=20
(so so that it doesn't look like I file all of them myself ;-)! Go to=20
jira.ddsteps.org, create an account if you don't already have one, and=20
fill in a request.

Please, let me know if this solved your problem and how it worked out!
