Message Manifest implementation

Implementing Message Manifest

There are three items to consider and recognize when implementing Message Manifest in a robotic solution.

  • How does Pega Robot Runtime™ manage Message Manifest definitions in a multi-project solution?
  • How does a developer use the MessageManifest component methods?
  • How does a developer pass and return a MessageDetails object?

Multi-project solutions at run time

Consider a solution that contains three projects. Each project has its own Message Manifest definitions created in the properties of each project.

  1. Pega Robot Runtime starts and loads the solution projects.
  2. Pega Robot Runtime merges the message definitions from each project into one message definitions store.
  3. The MessageManifest component in each project provides access to the one central message definitions store.

MessageManifest component methods

There are four MessageManifest component methods.

msg man methods
Method Description
GetMessage Returns the individual properties of the message definition for the specified message
GetMessageDetails Returns a MessageDetails object containing the individual properties for a message definition. Input values can be supplied for messages with substitution items
ShowMessage (1 parameter) Displays message based on MessageDetails object
ShowMessage (2 parameters) Displays message given its code and any inputs needed for substitution
Note: Both ShowMessage methods return a System.Windows.Forms.DialogResult object.

MessageDetails object

When the developer uses the GetMessageDetails method, it returns a MessageDetails object representing the specified message. The MessageDetails object exposes the message definition as properties.

As a result, an automation can pass the MessageDetails object as an automation output and as a Jump label input because both the Jump labels and Exit points support the MessageDetails object as a data type.
