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


[OmniFaces utilities] The createInfo() method creates an INFO faces message with the given message body which is formatted with the given parameters.
[OmniFaces utilities] The addInfo() method adds an INFO faces message to the given clientId, with the given message body which is formatted with the given parameters.

Method Messages#createInfo() - Create an INFO faces message with the given message body which is formatted with the given parameters.
See also: Faces#getContext()

Method Messages#addInfo() - Add an INFO 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 FILES_UPLOADED = "The {0} file and associated extensions ({1}, {2} and {3}) were successfully uploaded !";

import org.omnifaces.util.Messages;
...
// for a certain component, replace null with clientId
FacesMessage info = Messages.createInfo(FILES_UPLOADED, "SHP", "SHX", "DBF", "SBN");
// add the info FacesMessage to the current list of messages, or/and do some something else with it
Messages.add(null, info);
     
// or, if you just want to add it in the messages list, use directly Messages#addInfo()
// for a certain component, replace null with clientId
Messages.addInfo(null, FILES_UPLOADED, "SHP", "SHX", "DBF", "SBN");

Generated message:
The SHP file and associated extensions (SHX, DBF and SBN) were successfully uploaded !

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.
