Duplicate Result column on Decision Table
SA-9795
Summary
Developer noticed that on a decision table rule, checking "Allowed to return values" checkbox causes an additional Result column to be added to the table configuration.
On saving this erroneous result column is usually removed (but not always).Developers are using delegated decision rules and this behavior confuses them.
When testing with Chrome the behavior was slightly different in that the additional result column was there on creation of the rule and could not be removed.
