    <p>You're going to need a servlet for this. I've answered a Uploadify + Servlet question before which should give sufficient clues: <a href="https://stackoverflow.com/questions/2272160/uploadify-plugin-doesnt-call-java-servlet/2273711#2273711">Uploadify plugin doesn&#39;t call Java Servlet</a>. The concept is not that different for SWFUpload and YUI Uploader. Note that you can just put plain HTML in a JSF page without problems. </p> <p>Your main problem is enabling the JSF backing bean and the HTTP servlet to exchange data with each other. For this the HTTP session should be used. First let the JSF bean on initial request generate an unique key which is to be used as session attribute name:</p> <pre><code>key = UUID.randomUUID().toString(); </code></pre> <p>Then, in the upload URL which you tell Uploadify/SWFUpload/etc to use, you need to include the <code>jsessionid</code> URL fragment (so that the servlet will use the same HTTP session) and the <code>key</code>as URL query string parameter (so that the servlet will use this key to store relevant state about the file upload). Assuming that you need to specify it as a JS object key:</p> <pre><code>url: '${pageContext.request.contextPath}/uploadServlet;jsessionid=${pageContext.session.id}?key=&lt;h:outputText value="#{uploadBean.key}" /&gt;' </code></pre> <p>Now, the servlet will be invoked within the same HTTP session (i.e. <code>request.getSession()</code> will be exactly the same one as available in JSF by <code>ExternalContext#getSession()</code> and its attributes by <code>getSessionMap()</code>). So, in <code>doPost()</code> just do:</p> <pre><code>String key = request.getParameter("key"); request.getSession().setAttribute(key, someStateAboutTheUpload); </code></pre> <p>Finally, when JSF is about to process the form submit, just get the desired data by the key (which you store for the subsequent request by <code>&lt;input type="hidden"&gt;</code> or <code>&lt;t:saveState&gt;</code> in case of a request scoped bean):</p> <pre><code>SomeState someState = (SomeState) externalContext.getSessionMap().get(key); </code></pre> <p>The unique key is not necessary for the functioning, it can even be a static key, but a on per-view basis generated key ensures that the data doesn't clash when the enduser has the same view open in multiple browser tabs/windows in the same session.</p>

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.
