    <p>Based on <a href="https://stackoverflow.com/questions/2141464/how-to-access-complex-java-maps-in-jsf-richfaces">this question</a> I have a couple of other questions:</p> <p>1) the map in this question which is made available to jsf is actually one of a number, so i'm now not sure what the backing bean method's return type should now be. if i modify it's current <code>Array&lt;String&gt;</code> return type to <code>Array&lt;Map Integer, Map&lt;String, String[]&gt;&gt;&gt;</code> (or <code>ArrayList&lt;Map Integer, Map&lt;String, String[]&gt;&gt;&gt;</code> ?) would it just be a case of further nesting the iterator on the jsf side? Trouble is an Array/ArrayList isn't a Map and I'm unsure how this then looks in jsf. would this be correct: </p> <pre><code>&lt;c:forEach items="#{bean.map}" var="entry"&gt; &lt;!-- array --&gt; &lt;c:forEach items="#{entry.value}" var="nentry"&gt; &lt;!-- map --&gt; &lt;h:outputText value="Key: #{nentry.key}, Values:" /&gt; &lt;!-- integer --&gt; &lt;c:forEach items="#{nentry.value}" var="nnentry"&gt; &lt;!-- sub map --&gt; &lt;h:outputText value="Key: #{nnentry.key}, Values:" /&gt; &lt;!-- string --&gt; &lt;c:forEach items="#{nnentry.value}" var="nnnentry"&gt; &lt;!-- string[] --&gt; &lt;h:outputText value="#{nnnentry}" /&gt; &lt;/c:forEach&gt;&lt;br /&gt; &lt;/c:forEach&gt;&lt;br /&gt; &lt;/c:forEach&gt;&lt;br /&gt; &lt;/c:forEach&gt; </code></pre> <p>?</p> <p>2) what i'm really storing in this map is xpath rips from an XML DOM tree parsed on the java side. i'm now thinking i can access this java-based DOM tree from JSF directly without having to use XPath -> ArrayOfMaps and return that. In an XML file which looks something like this, is there a better way than using the above method?:</p> <pre><code> &lt;test&gt; &lt;testid&gt;1&lt;/testid&gt; &lt;testname&gt;myName&lt;/testname&gt; &lt;inst&gt; &lt;id&gt;1&lt;/id&gt; &lt;src&gt;C:\my\path&lt;/src&gt; &lt;mask&gt;.*\.\w{3}&lt;/mask&gt; &lt;mask&gt;.*\.x&lt;/mask&gt; &lt;/inst&gt; &lt;inst&gt; &lt;id&gt;2&lt;/id&gt; &lt;src&gt;C:\my\otherpath&lt;/src&gt; &lt;mask&gt;.*\.\w{3}&lt;/mask&gt; &lt;mask&gt;.*\.x&lt;/mask&gt; &lt;/inst&gt; &lt;/test&gt; </code></pre> <p>Thanks again Mark</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.
