HTML rules Completing the New or Save As form
About  New  HTML  Pages & Classes  History  More...

As a best practice, before creating a new HTML rule, it is strongly recommended that you investigate using an auto-generated section instead. The New form displays a message with information about that alternative.

Create an HTML rule by selecting HTML from the Technical category.

An HTML rule has two key parts:

Field	Description
Applies To	Select the name of the class that this rule applies to, typically the default source of property values for the JSP tags or directives in the rule. In the unusual situation that this rule is to be referenced in an activity but without an associated clipboard page, enter @baseclass as the class name. If this rule is to be referenced only with the <pega:include > JSP tag (or include directive) and has no associated page, do not create an HTML rule. For better performance, create an HTML fragment rule rather than an HTML rule. The classes you can enter here may depend on the RuleSet you select. On the Restrictions tab of the Class form, a class rule may limit rules applying to that class to belong to one of an explicit list of RuleSets.
Stream Name	Enter a name for this HTML rule. Begin the name with a letter and follow the rules for a Java identifier. See How to enter a Java identifier.

For general information about the New form, see Completing the new rule dialog box. For general information on the Save As form, see How to enter rule keys using Save As.

Rule resolution

Full rule resolution applies to HTML rules. When searching for HTML rules, the system:

• Filters candidate rules based on a requestor's RuleSet list of RuleSets and versions
• Searches through ancestor classes in the class hierarchy for candidates when no matching rule is found in the starting class
• Finds circumstance-qualified rules that override base rules
• Finds time-qualified rules that override base rules
