Locatable page

C-462 Advanced feature For most types of rules that reference properties, record in the rule form the name of the clipboard page that at runtime contains each property. Typically, list the names of pages that may be sources of property values on a Pages & Classes tab. Other pages are identified by a symbolic keyword such as primary for the primary page of an activity.

A capability called locatable pages reduces the need for pages to be explicitly named in the rule. Locatable pages can be used with these rule types:

Constraints (Rule-Declare-Constraints rule type)
Declare Expressions (Rule-Declare-Expressions rule type)
When conditions (Rule-Obj-When rule type)

References to properties on a locatable page use the locate keyword in lowercase as a prefix to or initial portion of the page name, as in:

locateCustomer.OrderAmount

At runtime, the system uses backward chaining and an activity with type Locate to find and (if necessary) add the proper page to the clipboard. This eliminates the need for the developer creating the when condition rule to specify the page.
