JSF 1.2 Message Group Component

See Also

The Message Group component message group icon provides a way to show a list of global messages for a page, such as system runtime errors, or a list of messages related to components. To show individual component errors, such as validation and conversion errors, clear the showGlobalOnly property in the Message Group Properties Window.

The two message components, Message Group and Message, display error messages concerning component rendering and validation.

To write your own text to this component, call info(String summary), warn(String summary), error(String summary), or fatal(String summary). The web application applies different styles to the text, depending on the method's severity level.

To write both a summary message and a detail message, use FacesContext.getCurrentInstance().addMessage(null, new FacesMessage(summary, detail)) or ValidatorException(new FacesMessage(severity, summary, detail)).

You must set the component's showDetail property for detail messages to appear.
