    <p>I am creating a simple Liferay Portlet and I cannot manage to get a name given in an input Box to get rendered. The main Portlet class is:</p> <pre><code>public class MyHelloWorldPortlet extends GenericPortlet { public void init() { editJSP = "/html/myhelloworldportlet/edit.jsp"; viewJSP = "/html/myhelloworldportlet/view.jsp"; } public void processAction( ActionRequest actionRequest, ActionResponse actionResponse) throws IOException, PortletException { String name = actionRequest.getParameter("name"); PortletPreferences prefs = actionRequest.getPreferences(); prefs.setValue("Name", name); prefs.store(); actionResponse.setPortletMode(PortletMode.VIEW); } public void doEdit( RenderRequest renderRequest, RenderResponse renderResponse) throws IOException, PortletException { include(editJSP, renderRequest, renderResponse); } public void doView( RenderRequest renderRequest, RenderResponse renderResponse) throws IOException, PortletException { PortletPreferences prefs = renderRequest.getPreferences(); String defaultValue = ""; String name = prefs.getValue("NAME", defaultValue); renderRequest.setAttribute("ATTRIBUTE_NAME", name); include(viewJSP, renderRequest, renderResponse); } protected void include( String path, RenderRequest renderRequest, RenderResponse renderResponse) throws IOException, PortletException { PortletRequestDispatcher portletRequestDispatcher = getPortletContext().getRequestDispatcher(path); if (portletRequestDispatcher == null) { _log.error(path + " is not a valid include"); } else { portletRequestDispatcher.include(renderRequest, renderResponse); } } protected String editJSP; protected String viewJSP; private static Log _log = LogFactoryUtil.getLog(MyHelloWorldPortlet.class); </code></pre> <p>}</p> <p>The edit.jsp file is:</p> <pre><code>&lt;form action="&lt;portlet:actionURL/&gt;" method="post" name="&lt;portlet:namespace/&gt;fm"&gt; &lt;label for="&lt;portlet:namespace/&gt;name"&gt;Name:&lt;/label&gt; &lt;input name="&lt;portlet:namespace/&gt;name" type="text"&gt; &lt;br/&gt;&lt;br/&gt; &lt;input type="submit" value="Add Name"&gt; &lt;/form&gt; </code></pre> <p>The view.jsp file is:</p> <pre><code>&lt;% String name = (String)request.getAttribute("ATTRIBUTE_NAME"); %&gt; &lt;p&gt;Hello &lt;%= name %&gt;!&lt;/p&gt; </code></pre> <p>The problem is that the output on the view is always Hello!. Not any name is passed to the output although the user enters one in the input Box. Why? </p>

    2. COAre you getting any value in `actionRequest.getParameter("name");`? On the other hand, i'm not sure if setting the preference with "Name" and recovering it with "NAME" is right.

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.
