[rules-users] Exception when building a template

Mon Apr 23 16:56:48 EDT 2012

I was using template to build the decision table type of rule editor. I
have switched to the "decision table" since then.

However since the template design allows me to achieve the decision table
look and feel, it would be great to allow us to define the display name of
the "column" as well.

Yes, since I was allowed to provide a nature context, the application
should either handle it or remind me that the value is not valid when I
define the template key, instead of giving me a exception.

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
