Messages are displayed via `<tc:messages/>` tag.

To create messages, press one of the following buttons. The message will be displayed in the tabgroup.

If you are using ajax, make sure to rerender the `<tc:message/>` tag.

On this tab, you can see how messages are displayed if no attribute are set for the `<tc:messages/>` tag.

A limit for the number of messages can be set with the `maxNumber` attribute.

    <tc:messages maxNumber="2"/>

The range, which severities are displayed, can be set with `minSeverity` and `maxSeverity`. In this example, only warnings and error should be displayed.

    <tc:messages minSeverity="#{messagesController.severityWarn}" maxSeverity="#{messagesController.severityError}"/>

A message can also contain 'details', you can show it with `showDetail`.

    <tc:messages showDetail="true"/>

In this example, only the details are shown. To hide the summary, use `showSummary`.

    <tc:messages showSummary="false" showDetail="true"/>

By default, messages are sorted by severity. Therefor, the `orderBy` attribute is not needed in this case.

    <tc:messages orderBy="severity"/>

Messages displayed in the order they occurred.

    <tc:messages orderBy="occurrence"/>
