Currently (as of 6.10.0) the JavaDoc on the FeedbackMessages#hasMessage(int) states that it returns true if and only if a message with the specified level was registered.
However it relies on FeedbackMessage#isLevel(int) which in turn return true if whether the message level is greater than or equal to the given level. Isn't that contradicting? I registered an Error message for my form field and I have a new behavior checking for Warnings that performs its duties because an Error message is at a lever greater than the Warning level. ~ Thank you, Paul Bors
