Using a Value List in Rules and Field Validations

irAuthor provides various features around a concept called a value list. Values lists are intended to be linked to fields that should have a distinct a set of values. These fields might show up in your application as drop down or list boxes. Values lists are intended to allow rule authors to do the following:

• Evaluate field(s) in a rule without having to worry about spelling and capitalization
• Set the value of a field by selecting from a set of valid values
• Easily validate fields by verifying that a value entered by a user is in the value list

Value lists are simply a list of values that are stored in the ruleapp or come from a database. They can optionally have descriptions associated with the values which is useful if the values are codes, abbreviations etc.

There are a variety of ways value lists can be used within irAuthor. The following examples use a value list of United States state codes that has been associated with the State/Province field:
