Error Panel Style Message Format:

Currently, I am utilizing PrimeFaces, which utilizes JQuery UI not just for its functionality but also for its CSS styling framework. The issue I am facing stems from my lack of understanding about the CSS framework, as I have been unable to locate any examples or documentation to assist me.

My goal is to apply the Theme's style for error messages to my own panel. Here is an example of what I am trying to achieve:

<p:panel rendered="#{bean.someError}"  styleClass="?? what goes here ??">
    <h:outputText styleClass="?? what goes here ??"
         value="Error! A parameter on this page is incorrect and cannot be displayed. This may be due to using an outdated bookmark." />
</p:panel>

I want it to resemble the error message style you would see when using . Any guidance would be greatly appreciated.

If you are struggling to style your components, one helpful resource is the PrimeFaces showcase. You can also use tools like Firebug to inspect the CSS classes being applied.

Consider using p:outputPanel with layout="block" instead of p:panel, as panels come with their own predefined styles. On the other hand, outputPanels with block layouts will render a div element without any extra styling.

Here's an example of how your code could be structured:

<p:outputPanel rendered="#{bean.someError}" layout="block" styleClass="ui-messages ui-widget">
     <div class="ui-messages-error ui-corner-all">
         <span class="ui-messages-error-icon"></span>
         <ul>
            <li>
                <span class="ui-messages-error-summary">
                    <h:outputText value="Error!  A parameter to this page is wrong so it can't
                                         be rendered.  This is probably because you used a
                                         stale bookmark." />

                </span>
           </li>
        </ul>
    </div>
</p:outputPanel>

Answer №2

When dealing with a single message, you only need the following:

<div class="message-container">
      <span class="error-icon"/>
      <span class="error-message-detail">write your message here</span>
</div>

This approach uses fewer tags compared to Damian's solution.
