                                 throws java.lang.IllegalStateException

      `ID` of the component that manages "rule context" for which this class participates. A non-Canvas class can only use the ruleScope for supporting `dynamic properties`. Unlike `Canvas.setRuleScope` `ruleScope` on a standalone class must be explicitly specified.
      Parameters:
        `ruleScope` - New ruleScope value. Default value is null
      Returns:
        `BaseClass` instance, for chaining setter calls
      Throws:
        `java.lang.IllegalStateException` - this property cannot be changed after the component has been created

    - #### getRuleScope

          public java.lang.String getRuleScope()

      `ID` of the component that manages "rule context" for which this class participates. A non-Canvas class can only use the ruleScope for supporting `dynamic properties`. Unlike `Canvas.setRuleScope` `ruleScope` on a standalone class must be explicitly specified.
      Returns:
        Current ruleScope value. Default value is null

    - #### addDynamicProperty

          public void addDynamicProperty(java.lang.String propertyName,
                                         java.lang.String source)

      Sets up the value of `propertyName` to be dynamically derived from the `ruleScope`, by either a simple `DataPath` into the ruleScope, an `AdvancedCriteria` built against `DataPaths`, or via a textual or numeric formula using the ruleScope as available formula inputs.

      The dataPath, criteria, or formula is evaluated immediately when addDynamicProperty() is called, then re-evaluated every time the ruleScope changes. An `AdvancedCriteria` will always evaluate to boolean true or false, and a `UserSummary` to a string.

      It is invalid usage to use `addDynamicProperty()` on a property that is not runtime settable. However, `addDynamicProperty()` will not throw an error or log a warning if this is done.

      If a property is already dynamic and addDynamicProperty() is called again, the new dynamic behavior replaces the old. If a property should no longer be dynamic, call `clearDynamicProperty()`.

      Dynamic properties can also be declared together via `dynamicProperties`.

      Note that you may convert a simple criteria to an `AdvancedCriteria` by calling `DataSource.convertCriteria()`.

      Parameters:
        `propertyName` - name of a settable property on this instance. See `Identifier`
        `source` - a `DataPath`

      Sets up the value of `propertyName` to be dynamically derived from the `ruleScope`, by either a simple `DataPath` into the ruleScope, an `AdvancedCriteria` built against `DataPaths`, or via a textual or numeric formula using the ruleScope as available formula inputs.
