[OmniFaces utilities 2.0]Create/add a parameterized global (or to the given client ID) FATAL faces message


[OmniFaces utilities] The createFatal() method creates a FATAL faces message with the given message body which is formatted with the given parameters.
[OmniFaces utilities] The addFatal() method add a FATAL faces message to the given clientId, with the given message body which is formatted with the given parameters.

Method Messages#createFatal() - Create a FATAL faces message with the given message body which is formatted with the given parameters.

Method Messages#addFatal() - Add a FATAL faces message to the given clientId, with the given message body which is formatted with the given parameters.
See also: Faces#getContext()
Usage:

private static final String USER_FATAL = "The database at {0} does not respond on port {1} !";

import org.omnifaces.util.Messages;
...
// for a certain component, replace null with clientId
FacesMessage fatal = Messages.createFatal(USER_FATAL, "89.38.122.5", "5432");
// add the fatal FacesMessage to the current list of messages, or/and do some something else with it
Messages.add(null, fatal);

// or, if you just want to add it in the messages list, use directly Messages#addFatal()
// for a certain component, replace null with clientId
Messages.addFatal(null, USER_FATAL, "89.38.122.5", "5432");

Output:
The database at 89.38.122.5 does not respond on port 5432 !

Note Don't forget to use in page where the messages are displayed the <h:messages>, for global messages, <h:message>, for component messages, or any other approach capable to display the messages.

Note By default, this example uses the OmniFaces default message resolver, but you can use your own message resolver as in Working with OmniFaces Message Resolvers.
