<p>Render a single message for a specific component.</p><p>Set-up for Rendering</p><ul><p>Obtain the "summary" and "detail" properties from<code>UIMessage</code> component. If not present, keep the empty string as the value, respectively. Obtain the first<code>FacesMessage</code> to render from the component, using the "for" property of the <code>UIMessage</code>. This will be the only message we render. Obtain the severity style for this message. If the severity of the message is<code>FacesMessage.SEVERITY_INFO</code>, the severity style comes from the value of the "infoStyle" attribute. If the severity of the message is<code>FacesMessage.SEVERITY_WARN</code>, the severity style comes from the value of the "warnStyle" attribute, and so on for each of the severities, <code>INFO, WARN, ERROR</code> and<code>FATAL</code>. The same rules apply for obtaining the severity style class, but instead of "infoStyle, warnStyle", etc use "infoClass, warnClass", etc. Obtain the "style", "styleClass" and "layout" attributes from the<code>UIMessage</code> component. If we have a "style" attribute and a severity style attribute, use the severity style attribute as the value of the "style" attribute. If we have no "style" attribute, but do have a severity style, use the severity style as the value of the "style" attribute. The same precedence rules apply for the style class.</p></ul><p>Rendering</p><ul><p>For the message renderer, we only render one row, for the first message. For the messages renderer, we render as many rows as we have messages. If either of the "style" or "styleClass" attributes has a non-null value (as determined above), render a "span" element, outputting the value of the "style" attribute as the the value of the "style" attribute, and outputting the value of the "styleClass" attribute as the value of the "class" attribute on the "span" element. If the<code>UIMessage</code> has a "tooltip" attribute with the value of "true", and the <code>UIMessage</code> has "showSummary" and "showDetail" properties with the value "true", if we haven't already written out the "span", output the "summary" as the value of the "title" attribute on the "span". If we haven't already written out a "title" attribute, and "showSummary" is true, output the summary. If "showDetail" is true, output the detail. Close out the span if necessary.</p></ul>
