RE: Unable to read portlet preferences with Spring 2.5

Got it!

Preferences are read when the portlet is put on the page. Since the preferences were added after the portlet was put on a page, they were not available.

Removing the portlet and putting a fresh instance on a page resolved my problem.

Thanks for reading. :-)

Unable to read portlet preferences with Spring 2.5

2009-07-21T14:21:56Z

Hi,

I'm trying to read the portlet settings using Spring Portlet MVC 2.5, but so far no luck.

My portlet.xml with preferences is:


<!--?xml version="1.0" encoding="UTF-8"?-->

<portlet-app xmlns="http://java.sun.com/xml/ns/portlet/portlet-app_1_0.xsd" version="1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemalocation="http://java.sun.com/xml/ns/portlet/portlet-app_1_0.xsd
                        http://java.sun.com/xml/ns/portlet/portlet-app_1_0.xsd">

    <portlet>
        <description>Portlet displaying the user account summary</description>
        <portlet-name>user-account-portlet</portlet-name>
        <display-name>User account summary</display-name>

        <!--  <portlet-class>nl.detelefoongids.oase.portlet.BasePortlet</portlet-class>  -->
        
        <portlet-class>org.springframework.web.portlet.DispatcherPortlet</portlet-class>
        <init-param>
            <name>contextConfigLocation</name>
            <value>/WEB-INF/context/baseportlet.xml</value>
        </init-param>
        

        <supports>
            <mime-type>text/html</mime-type>
            <portlet-mode>view</portlet-mode>
            <portlet-mode>edit</portlet-mode>
        </supports>

        <supported-locale>en</supported-locale>

        <portlet-info>
            <title>User account summary</title>
            <short-title>User account summary</short-title>
            <keywords>base default portlet user account summary</keywords>
        </portlet-info>

        <portlet-preferences>
            <preference>
                <name>test</name>
                <value>123456test</value>
            </preference>
        </portlet-preferences>
    </portlet>
</portlet-app>

The code to read them is:


package customer.packagename;

import javax.portlet.PortletPreferences;
import javax.portlet.PortletRequest;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
@RequestMapping(value = "EDIT")
public class DefaultEditController {

    @RequestMapping
    public String handleActionRequest(ModelMap model, PortletRequest request) {

        PortletPreferences preferences = (PortletPreferences)request.getPreferences();
        System.out.println("Action: Preferences = " + preferences);
        System.out.println("Action: Preferences map leeg? = "+ preferences.getMap().isEmpty());
        System.out.println("Action: Preferences - test = " + preferences.getValue("test", "default value"));
        System.out.println("Action: Preferences - presentation = " + preferences.getValues("presentation", new String[]{"1"}).length);
        
        // model.addAttribute("test", preferences.getValue("test", "not set!"));
        return "edit";
    }
}

Somehow the map is always empty and so the values passed as 'default value' are always returned (and not the '123456test' as I was hoping for).

What am I doing wrong?! This problem has cost me all day... and I'm starting to get depressed.
