Constructing Error Text Strings

Guidewire recommends that you use the DisplayKey class to return the value to use for the strErrorReason and strWarningReason. For example, the following code returns the message, “User has duplicate roles”.

USES:
uses gw.api.locale.DisplayKey

CONDITION (...):
...

ACTION (...):
DisplayKey.get("Java.Admin.User.DuplicateRoleError")

This also works with display keys that require a parameter or parameters. For example, display_languageCode.properties defines the following display key with placeholder {0}:

Java.UserDetail.Delete.IsSupervisorError = Cannot delete user because that user is the supervisor
      of the following groups\: {0}

Code DisplayKey.get("Java.UserDetail.Delete.IsSupervisorError",GroupName) then returns the message (with the rule retrieving the value of GroupName already):

Cannot delete user because they are supervisor of the following groups: Western Region”
