Body
I have DTO which contains itself (it is nested). <pre><code>public class MyDTO { private SomeData someData; private MyDTO nested; // getters and setters } </code></pre> I created composite component, which is calls itself recursively. I call it like this: <pre><code><screen:my-dto-screen dto="#{myDTOBean.myDto}" /> </code></pre> The definition is: <pre><code> <composite:interface> <composite:attribute name="dto"/> </composite:interface> -- display "someData" here -- <p:panel rendered="#{cc.attrs.dto.nested != null}" /> -- this acts as recursion bottom -- <screen:my-dto-screen dto="#{cc.attrs.dto.nested}" /> </p:panel> <composite:implementation> </code></pre> The real code is not simple as this, but I wrote this in order to give you a simple idea what the problem is about. Everything seems fine, but I get some strange exceptions in view. <pre><code>javax.servlet.ServletException javax.faces.webapp.FacesServlet.service(FacesServlet.java:422)

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.
