The NameValuePair object contains a display name associated with a value. The actuate.parameterDefinition.setSelectNameValueList( ) function takes an array of actuate.parameter.NameValuePair objects to use in a selection list. In this way, a ParameterDefinition can display a list of names and map them to values used internally. For example, set the name "My Default Country" for a NameValuePair to display "My Default Country" in the drop-down list in the interface, and set the value to "United States" internally for a US user.
