When it comes to develop a JSF page, it happens for error message a component/view to have a messages that tell the user about some missing or wrong data must be provided/fixed to ensure that the business logic for your managed beans can execute smoothly and without any problems. The message/messages component provides the capability for the developer to provide the desired style for the different kind of messages, message from backing so the styles for different messages can provide a deep identification in which the user can discriminate between those that are just providing an information from those that couldn't proceed any further if they aren't fixed. The severity level which passed through adding a faces message into component/view determine the type of the messages whether they are error or even just an information. Any message/messages contains either type of information; detail and summary, where the developer has controlled if it does wish to render the detail alone or the summary alone or it has the both. One remaining important issue, in that when it comes to use the message/messages, the bundled messages are brought for making a localization of component/view messages.

Unless you know something I don't, you'd normally code more like this: First of all, the "id" attribute MUST be unique within its container and I'm not sure how you even get the page to compile otherwise. That's a basic restriction that's part of JSF's XML heritage. Secondly, the "for=" attribute on a message is supposed to bind the message to the (unique) id of a specific control. Thirdly, as in the example, required items are so fundamental that JSF is capable of handling them without any Java code at all, at least if you can endure the limitations in the generated message. Typically you'd use the JSF context addMessage to enter messages that aren't tightly bound to specific controls and that would be presented by the element. Validation messages are normally created during the validation phase of the JSF lifecycle, and if a validation fails, that causes the lifecycle to be altered. None of the bean data will be updated and the action pr
