<h2>Checking the source of the errors</h2> <p>Those exceptions are most likely only the symptom of the real cause. To be sure, change the your <code>log4j.xml</code> and <code>properties-local.xml</code> per the <a href="http://wiki.orbeon.com/forms/doc/developer-guide/xforms-logging#TOC-Development-configuration" rel="nofollow">development configuration</a>, reproduce the problem, and check again your <code>orbeon.log</code>. Check if in the log you see now see an <code>java.lang.NoClassDefFoundError: oracle/xdb/XMLType</code> exception.</p> <h2>Solution</h2> <p>If you see that <code>NoClassDefFoundError</code>, you need to add the <code>xdb.jar</code> and <code>xmlparserv2.jar</code> to the directory where you currently have Oracle driver. Those two files are part of the Oracle driver, and come along the other "main jar", i.e. <code>ojdbc6_g.jar</code>. On Tomcat, you typically place those files in Tomcat's <code>lib</code> directory. Restart Tomcat, and your problem should be solved.</p> <h2>Why this is happening</h2> <p>This is happening because Orbeon Forms 4.4 started sending XML "as XML" to Oracle, instead of "as CLOB". Because of this, the driver uses classes from <code>xdb.jar</code> and <code>xmlparserv2.jar</code>. In retrospect, this might not have been the best approach; it was done because it looked like the "right thing", but it isn't clear this has any performance or other benefit, and makes installation and upgrade harder, requiring additional jars.</p> <h2>Update</h2> <p>This issue is <a href="https://github.com/orbeon/orbeon-forms/issues/1484" rel="nofollow">fixed in Orbeon Forms 4.5</a>.</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.
