Creating Declare OnChange rules
Records can be created in various ways. You can add a new record to your application or copy an existing one. You can specialize existing rules by creating a copy in a specific ruleset, against a different class or (in some cases) with a set of circumstance definitions. You can copy data instances but they do not support specialization because they are not versioned.
Create a Declare OnChange rule by selecting
Declare OnChange
from the
Decision
category.
Key parts:
A Declare OnChange rule has two key parts:
| Field | Description |
| Apply to |
Select a class for this rule. At runtime, a clipboard page of this class must be a top-level page. The properties to be watched may be in this class (or in the class of an embedded page).
You cannot use a Rule-Declare-* class or any ancestor of the Rule-Declare- class (including @baseclass ) here. You cannot use a class derived from the Code- or Embed- class here. |
| Identifier |
Enter a unique name for this OnChange rule within the class. Begin the name with a letter and use only letters, numbers, the ampersand character, and hyphens.
No other rules explicitly reference this Identifier value. However, because of normal class inheritance, a Declare OnChange rule named OutofStock at one level in the class structure may override (and so prevent execution of) a Declare OnChange rule named OutofStock at a higher level in the class structure. |
