[OmniFaces utilities 2.0] Add a parameterized global ERROR faces message


[OmniFaces utilities] The addGlobalError() method adds a global ERROR faces message, with the given message body which is formatted with the given parameters.

Method:
Usage:

private static final String FILES_UPLOADED_ERROR = "The {0} file cannot be uploaded ! File size should be smaller than {1} bytes !";

import org.omnifaces.util.Messages;
...
Object[] params = new Object[]{"order.txt", 1024};
Messages.addGlobalError(FILES_UPLOADED_ERROR, params);
// or
Messages.addGlobalError(FILES_UPLOADED_ERROR, "order.txt", 1024);

Output:
The order.txt file cannot be uploaded ! File size should be smaller than 1,024 bytes !

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