    <p>First I ask a question then I am giving the answer. In this post my intention is to just share my experience that what's the problem that I faced and how I get rid off from that problem. In my question I said that the only hitch in my application is that size of first page in not large as I mentioned and other pages are according to my command. Now solution is just we have set the page size before document.open() and problem solve.</p> <pre><code> public class pdfPortlet extends MVCPortlet { public void serveResource(ResourceRequest req, ResourceResponse res) throws PortletException, IOException { if(req.isUserInRole("administrator")) { try { adminMethod(req,res);

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.
