    <p><strong>Problem:</strong><br/> i) In a JSF2 application, I want to create a page with a tab control, where, when the user clicks on a tab, the contents for the panel below is loaded from an xhtml file in the server through an ajax call.<br/> ii) I want this to support graceful degradation (when Javascript is disabled), so that upon clicking the tab, an HTTP request is fired, and a new page is loaded...or the other way round, through progressive enhancement.<br/></p> <p><strong>Partial solutions:</strong> i) I guess I can accomplish this through the code example posted by BalusC in <a href="https://stackoverflow.com/questions/7737759/how-to-ajax-jsf-2-outputlink">How to ajax jsf 2 outputLink</a><br/> :-</p> <pre><code>&lt;h:form&gt; &lt;f:ajax render=":include"&gt; &lt;h:commandLink value="Home" action="#{menuManager.setPage('home')}" /&gt;&lt;br /&gt; &lt;h:commandLink value="FAQ" action="#{menuManager.setPage('faq')}" /&gt;&lt;br /&gt; &lt;h:commandLink value="Contact" action="#{menuManager.setPage('contact')}" /&gt;&lt;br /&gt; &lt;/f:ajax&gt; &lt;/h:form&gt; &lt;h:panelGroup id="include"&gt; &lt;ui:include src="#{menuManager.page}.xhtml" /&gt; &lt;/h:panelGroup&gt; </code></pre> <p><strong>Question</strong><br/> How can I extend this to solve problem (ii) Or is there any other completely different method? I think <em>maybe</em> I could achieve this with a noscript, but can't figure out how!</p> <p><strong>EDIT: Possible solution - yet to verify</strong>:<br/> The above code should work even if ajax is disabled; it should just work through HTTP, according to <a href="http://www.laliluna.de/articles/posts/jsf-2-evaluation-test.html" rel="nofollow noreferrer">http://www.laliluna.de/articles/posts/jsf-2-evaluation-test.html</a> :) <br/> Elegant! I'll try it out.</p>

    1. COWhat? You have users who have Javascript disabled? I'd rather upgrade the users...

    2. COAre you sure you want to invest a lot of time and effort into handling users whose browsers have disabled javascript? According to [this Yahoo study](http://developer.yahoo.com/blogs/ydn/posts/2010/10/how-many-users-have-javascript-disabled/), that's about 1%. I'm just sayin'.

    3. COI need to support a wide range of users, and ones on tiny screen devices (many of which lack js) too. I wouldn't bother to devote too much effort into this (redirecting to a different version of my application and such), and do as much as possible through code reuse. Hence my question. :)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
