Question

I do the front end HTML for a JSF team. I often run into the JSF tags being used rendering HTML of their own. It’s often a SPAN and isn’t usually a problem, but once in a while we have this:

<table>
<h:panelGroup rendered="[jsf logic]">
    <tr><td>#{jsfVariable}</td></tr>
</h:panelGroup>
</table>

Which will render this:

<table>
<span>
    <tr><td>Hello World.</td></tr>
</span>
</table>

I’ve been reading through JSF tag documentation but can’t find a specific mention of a way to tell the JSF tag to only render the child HTML, not the tag itself as an HTML element. Is there a JSF attribute to tell it “don’t render a span”? Or is there a JSF tag that will not render as HTML, but still allow for use of JSF variables within?

Answer 1

The <span> is only generated if you give the <h:panelGroup> an attribute which must end up in HTML, such as id, styleClass, etc. In your given example, the <h:panelGroup> has only a rendered attribute, so nothing will be generated to the HTML.

So, to achieve your requirement, just remove all attributes other than rendered from the <h:panelGroup>, exactly as you did in your own question example.
