    <blockquote> <p><em>I tried making a composite component that called itself recursively if the node had more children. I did this via and -- surprise! -- this resulted in an infinite loop and a stack overflow.</em></p> </blockquote> <p>It failed because <code>rendered</code> attribute isn't evaluated during building the JSF component tree, but only during generating the HTML output. You basically need JSTL <code>&lt;c:if&gt;</code> instead of <code>&lt;some:component rendered&gt;</code>. <a href="https://stackoverflow.com/questions/3342984/jstl-in-jsf2-facelets-makes-sense">It runs during building the JSF component tree</a>, so you don't end up in infinitely including the composite itself.</p> <hr> <blockquote> <p><em>The project already has PrimeFaces installed, so I'm looking at PrimeFaces Tree and TreeNode. But that doesn't quite feel right; I don't want the tree nodes to be expandable in the user interface. I want everything to be fully expanded.</em></p> </blockquote> <p>The JSF utility library <a href="http://omnifaces.org" rel="nofollow noreferrer">OmniFaces</a> has exactly the component you're looking for, the <code>&lt;o:tree&gt;</code>. That component doesn't generate any HTML markup by itself, so you've all the freedom to declare the HTML/JSF markup the way you want, also for specific depth levels.</p> <p><a href="http://showcase.omnifaces.org/components/tree" rel="nofollow noreferrer">Here's the showcase example</a>. Note the links at the bottom of the page, they point to the source code which may be helpful/interesting as learning exercise. It isn't exactly trivial as you perhaps initially thought while developing the composite (which is after all not exactly <a href="https://stackoverflow.com/questions/6822000/when-to-use-uiinclude-tag-files-composite-components-and-or-custom-componen/6822269#6822269">the right tool for the job</a>).</p> <p>As to distinguishing leaf nodes, the <code>&lt;o:tree&gt;</code> offers this possibility as follows:</p> <pre><code>&lt;o:tree value="#{bean.tree}" var="item" varNode="node"&gt; &lt;o:treeNode&gt; &lt;o:treeNodeItem&gt; &lt;ui:fragment rendered="#{not node.leaf}"&gt; ... &lt;/ui:fragment&gt; &lt;ui:fragment rendered="#{node.leaf}"&gt; ... &lt;/ui:fragment&gt; &lt;o:treeInsertChildren /&gt; &lt;/o:treeNodeItem&gt; &lt;/o:treeNode&gt; &lt;/o:tree&gt; </code></pre>

    2. CO@Alex: you're not the first who reported that: https://code.google.com/p/omnifaces-showcase/issues/detail?id=3 Cause is yet undetermined. I can't really help as I never encountered it and I am not able to beam over myself to problematic machines to investigate it myself because the reporters are unable to naildown/describe the cause. I suspect something related to OS based SSL store. Try a different machine/OS/network.

    3. COlooks like it is related to Windows XP (SP3 in my case), working under Windows 2008 Standard Server, same browser, same network, if it can help you out!

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).
