This function sends a message to clients running under the Gateway, or to a project within the Gateway itself. To handle received messages, you must set up event script message handlers within a project. These message handlers run Jython code when a message is received. You can add message handlers under the "Message" section of the client/Gateway event script configuration dialogs.
Note that messages cannot received within a Designer. However, messages can be sent within the Designer in a script (assuming that read/write comm is enabled).
This scripting function has no Client Permission restrictions.
