[rules-users] Exception when building a template

Mon Apr 23 04:33:50 EDT 2012

Hello,

Are you using a Rule Template or Decision Table? Your post states "template
(decision table)" but these are two different things entirely.

That aside, it does sound like a bug - you should either not be able to
define invalid column names in Guvnor or we should provide a means to
protect against internal limitations (e.g. invisibly munge the
user-provided column title into one that is valid at compile time). Can you
please raise a JIRA https://issues.jboss.org/browse/GUVNOR and attach a
repository export demonstrating the problem.

Thanks,

Mike
