public interface RuleCriteria
Canvas.ruleScope, so can set
Criterion.fieldNameto a path that references state in the current rule context.
Because this type of criteria are allowed to reference UI state (such as whether any records are selected in an adjacent grid) they are not generally used to filter DataSource records, since such criteria would not be able to be evaluated on the server.
All RuleCriteria are also
Dynamic Criteria unless otherwise noted.
