Use a declare pages rules to define the contents of a clipboard page that is to be available in read-only mode to multiple requestors in your application. For example, a page may contain daily prices for a set of commodities, bonds, or currencies, an organization chart, or quantity-on-hand inventory data extracted hourly (rather than in real time on-demand) from an external system. These pages can be "global", available to all requestors on a node.
Pages created by declare pages rules are called declarative pages.
Many rule types can reference the pages created by declare pages rules, and the properties on such pages; they do not explicitly reference the rule.
Declarative pages are created only when requested — the first time a requestor attempts to access a property value on the page. Each page created and maintained by a declare pages rule has
a name that starts with the prefix Declare_. Rules
of any type that can reference properties on pages other than
the current or primary page — including activities,
decision rules, parse rules — can reference properties on
these pages in a read-only or "right-hand" context.
Typically, the rule form identifies the name and class of a
declarative page on the Pages &
Classes tab.
On the Advanced tab of the Property form for a Page List or Page Group property, you can reference a Declare Pages rule that auto-populates the property with values.
Use the Application Explorer to view Declare Page rules that are part of your current application. Use the Rules by Type Explorer to list all the Declare Page rules the you may access.
Declare Pages rules are instances of the Rule-Declare-Pages class. They are part of the Technical category.
