[rules-users] List of valid values

[Chris Selwyn]

  Hi Vincent,

Thanks for the response.

I think that I was wondering about whether a Guvnor enumeration was 
usable at runtime (maybe by a DRL function) as well as being used for 
driving a Guvnor dropdown list in the guided editor.
Do you know whether it is possible?
