[rules-users] Guvnor enumerations

[Stephen Masters]

I have raised 4 Jira issues to cover the different specific bugs I have found.

GUVNOR-1997 - Enumerations editor fails to parse enums if there is a space prior to ":"
GUVNOR-1998 - Enumerations editor can't handle more than 15 enums in one file
GUVNOR-1999 - Enumerations editor attempts to display comments as enumerations
GUVNOR-2000 - Guvnor no longer supports external source data enumerations

The first three are pretty clear in what's wrong and have workarounds, but GUVNOR-2000 is the big one for me, which could prevent me from migrating from 5.3. I don't suppose anybody has actually been able to use externally sourced data enumerations in 5.5? Any workarounds?
