configuration page invisible

[Jerome Comouth, modificado 9 Anos atrás.]

I followed this article. I can choose the tab 'setup', but the content of the tab is blank (only on the right sight a link "Archive/Restore Setup").
Maybe you could tell me, if I made something wrong:
liferay-portlet.xml

<configuration-action-class>de.pax.qm.portlet.flra.Configuration</configuration-action-class>

config.jsp

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>

<%@ taglib uri="http://liferay.com/tld/portlet" prefix="liferay-portlet" %>
<%@ taglib uri="http://liferay.com/tld/theme" prefix="liferay-theme" %>
<%@ taglib uri="http://liferay.com/tld/aui" prefix="aui"%>

<%@ page import="javax.portlet.PortletPreferences"%>
<%@ page import="com.liferay.portal.kernel.util.Constants" %>
<%@ page import="com.liferay.portal.kernel.util.GetterUtil" %>
<%@ page import="com.liferay.portal.kernel.util.StringPool" %>

<liferay-theme:defineobjects />

<liferay-portlet:actionurl portletConfiguration="true" var="configurationURL" />

&lt;%
PortletPreferences prefs = renderRequest.getPreferences();
boolean showLocationAddress_cfg = GetterUtil.getBoolean(prefs.getValue("showLocationAddress", StringPool.TRUE));
%&gt;

<aui:form action="<%= configurationURL %>" method="post" name="fm">
    <aui:input name="<%= Constants.CMD %>" type="hidden" value="<%= Constants.UPDATE %>" />

    <aui:input name="preferences--showLocationAddress--" type="checkbox" value="<%= showLocationAddress_cfg %>" />

    <aui:button-row>
       <aui:button type="submit" />
    </aui:button-row>
</aui:form>

portlet.xml
<init-param>
<name>config-template</name>
<value>/views/config.jsp</value>
<!-- <name>view-template</name>
<value>/views/scan.jsp</value> -->
</init-param>

I combined init.jsp and config.jsp, so I don't need to create a jsp more. Maybe there is the mistake? Is there a possibility to search for errors, if there are no one displayed in the log file?

<configuration-action-class> entry you provided is custom class, can you provide code of that? Itseems that class is not implemented properly.

[Jerome Comouth, modificado 9 Anos atrás.]

The class is copy pasted from the tutorial, I can't see a problem there.
Thank you for the reply, Pankaj

import javax.portlet.ActionRequest;
import javax.portlet.ActionResponse;
import javax.portlet.PortletConfig;
import javax.portlet.PortletPreferences;
import com.liferay.portal.kernel.portlet.DefaultConfigurationAction;

public class Configuration extends DefaultConfigurationAction  {
	
	@Override
    public void processAction(
        PortletConfig portletConfig, ActionRequest actionRequest,
        ActionResponse actionResponse) throws Exception {

        super.processAction(portletConfig, actionRequest, actionResponse);

        PortletPreferences prefs = actionRequest.getPreferences();

        String showLocationAddress = prefs.getValue(
            "showLocationAddress", "true");

        System.out.println("showLocationAddress=" + showLocationAddress +
            " in ConfigurationActionImpl.processAction().");
    }

}

No need to create custom configuration class if you just want to store text value preferences. Use default configuration class instead.

<configuration-action-class>com.liferay.portal.kernel.portlet.DefaultConfigurationAction</configuration-action-class>

On submit action DefaultConfigurationClass will store all request parameters which are having preferences--xxx-- pattern.

Nevermind, I followed this article and everything worked fine, thanks.
