Use the Siblings display to understand rule resolution

Updated on September 13, 2021


A developer asks: Is there a way to visually display what occurs during rule resolution?

When looking at one rule, how can I determine which other rules might be selected by rule resolution processing rather than the current one? 


When a rule is open in the developer portal, the toolbar contains a Siblings button.

Click that button to view a table of all rules that are contenders with the open rule during rule resolution.

The table shows rules that match on name but differ on RuleSet and/or class.  The table uses shading to indicate that certain rules are not be reachable at all by rule resolution.
