More on Rule Properties (Data Paths, Expressions, and Contexts)
Yuval over at NextGen Consulting has a couple of good posts on Data Paths and Expressions and Path Contexts.
Paths are classically used in RuleManager properties, aliases, and auto-destination rules. More contemporary uses include CBO queries, Smart Client forms, and routing rules.
A bunch of good information there – go check it out.
I’ve also added links back to those posts on the Rulemanager wiki.
