Render a single message for a specific component.
Set-up for Rendering
Obtain the "summary" and "detail" properties fromUIMessage component. If not present, keep the
empty string as the value, respectively. Obtain the firstFacesMessage to render from the component, using
the "for" property of the UIMessage. This will be
the only message we render. Obtain the severity style for this
message. If the severity of the message isFacesMessage.SEVERITY_INFO, the severity style
comes from the value of the "infoStyle" attribute. If the
severity of the message isFacesMessage.SEVERITY_WARN, the severity style
comes from the value of the "warnStyle" attribute, and so on for
each of the severities, INFO, WARN, ERROR andFATAL. 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 theUIMessage 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.
Rendering
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 theUIMessage has a "tooltip" attribute with the value of
"true", and the UIMessage 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.
This renderer is not responsible for rendering its children.
Attributes with a pass-through value of
true are not interpreted by the renderer and are passed
straight through to the rendered markup, without checking for validity. Attributes with a
pass-through value of false are interpreted
by the renderer, and may or may not be checked for validity by the renderer.
