    <p>I have Java classes with the following structure (the class names do not imply anything, I was just making them up).</p> <pre><code>package test; import java.util.ArrayList; import java.util.List; import javax.xml.bind.JAXBContext; import javax.xml.bind.JAXBException; import javax.xml.bind.Marshaller; import javax.xml.bind.annotation.XmlAccessType; import javax.xml.bind.annotation.XmlAccessorType; import javax.xml.bind.annotation.XmlAttribute; import javax.xml.bind.annotation.XmlElement; import javax.xml.bind.annotation.XmlElementWrapper; import javax.xml.bind.annotation.XmlRootElement; import javax.xml.bind.annotation.XmlValue; @XmlRootElement public class Test { @XmlAccessorType(XmlAccessType.FIELD) static class Machine { @XmlElementWrapper(name="servers") @XmlElement(name="server") List&lt;Server&gt; servers = new ArrayList&lt;Server&gt;(); } @XmlAccessorType(XmlAccessType.FIELD) static class Server { Threshold t = new Threshold(); } @XmlAccessorType(XmlAccessType.FIELD) static class Threshold { RateThreshold load = new RateThreshold(); } @XmlAccessorType(XmlAccessType.FIELD) static class RateThreshold { @XmlAccessorType(XmlAccessType.FIELD) static class Rate { int count; Period period = new Period(); } @XmlAccessorType(XmlAccessType.FIELD) private static class Period { @XmlAttribute private String type = "second"; @XmlValue private float period; } Rate min = new Rate(); Rate max = new Rate(); } @XmlElementWrapper(name="machines") @XmlElement(name="machine") List&lt;Machine&gt; machines = new ArrayList&lt;Machine&gt;(); public static void main(String[] args) { Machine m = new Machine(); Server s = new Server(); s.t.load.max.count = 10; s.t.load.min.count = 1; m.servers.add(s); Test t = new Test(); t.machines.add(m); JAXBContext jaxbContext; Marshaller marshaller; try { jaxbContext = JAXBContext.newInstance(Test.class); marshaller = jaxbContext.createMarshaller(); marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true); marshaller.marshal(t, System.out); } catch (JAXBException e) { e.printStackTrace(); } } } </code></pre> <p>The problem I am having is with the XML output generated by JAXB when marshalling a Test instance. The XML output would always look like the following:</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8" standalone="yes"?&gt; &lt;test&gt; &lt;machines&gt; &lt;machine&gt; &lt;servers&gt; &lt;server&gt; &lt;t&gt; &lt;load&gt; &lt;min&gt; &lt;count&gt;1&lt;/count&gt; &lt;period type="second"&gt;0.0&lt;/period&gt; &lt;/min&gt; &lt;max&gt; &lt;count&gt;10&lt;/count&gt; &lt;period type="second"&gt;0.0&lt;/period&gt; &lt;/max&gt; &lt;/load&gt; &lt;/t&gt; &lt;/server&gt; &lt;/servers&gt; &lt;/machine&gt; &lt;/machines&gt; &lt;/test&gt; </code></pre> <p>As you can see, some elements are not being indented properly (that is, the deepest elements, count and period). Why is that? Is there something wrong with the way I created the JAXB context? Or is there a maximum limit to how many elements that can be indented recursively by JAXB? How could I fix this? Note that I have also set JAXB_FORMATTED_OUTPUT to true, but still get the improper indentation.</p> <p>Thanks.</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.
