Jeff,
When you use templates, the number of columns inside the derived rules
table should be exactly the same as in the template. In your situation
you created a RuleFamily with a Condition that is expected two sub-
columns: one for an operator and one for a value. By some reason your
condition has 3 columns but you merged first two columns, so they look
like two columns. Please un-merge and remove one unnecessary column
and your rule family should work fine.
We agree that OpenRules should catch such situations and produce much
friendlier message (or even allow such "hidden" merge). We will try to
improve it in the next release.
Thank you, and let us know if it fixes your problem.
