RE: Portlet problem

[veronica medeiros, modifié il y a 11 années.]

I followed the example http://www.opensource-techblog.com/2012/08/creating-custom-liferay-mvc-portlet.html to make a first portlet with value in input.
What I want to do: when typing the name in the input, click the button and show the name entered appear in front of the phrase NAME: _ (typed name) _ ... But that does not happen, someone help me please...

codes:

view.jsp

<%@ taglib uri="http://java.sun.com/portlet_2_0" prefix="portlet" %>

NAME:  ${userName}

<portlet:defineobjects />

<portlet:actionurl name="addName" var="addNameUrl"></portlet:actionurl>

<form action="${addNameUrl}" method="post">
<input type="text" name="userName"> 
<input type="submit">
</form>  

classe Name.java

package com.companyname.portlet;
import java.io.IOException;
import javax.portlet.ActionRequest;
import javax.portlet.ActionResponse;
import javax.portlet.PortletException;
import javax.portlet.ProcessAction;
import javax.portlet.RenderRequest;
import javax.portlet.RenderResponse;
import com.liferay.portal.kernel.util.ParamUtil;
import com.liferay.portal.kernel.util.StringPool;
import com.liferay.util.bridges.mvc.MVCPortlet;

public class Name extends MVCPortlet {

		public void doView(RenderRequest renderRequest,
				RenderResponse renderResponse) throws IOException, PortletException {
			super.doView(renderRequest, renderResponse);
		}
		
	@ProcessAction(name="addName")  
    public void addName(ActionRequest actionRequest,  
      ActionResponse actionResponse) throws IOException, PortletException{  
     String userName = ParamUtil.get(actionRequest, "userName", StringPool.BLANK);  
     actionRequest.setAttribute("userName", userName);  
    }   
}

Hi,

What i can understand id you want to see the typed name in the label.
As you can see that both the functionalities like submitting the form and getting values belongs to one portlet. so in this way you won't be able to retrieve that because when you submit that page portlet refresh and calls render method. One way to achieve this by using PortlalPrefrences.


Thanks,
Mohit

As Nilang said, If you are using liferay portal 6.2, you need to set one property in liferay-portlet.xml file to make it work-

<requires-namespaced-parameters>false</requires-namespaced-parameters>

[Nilang I Patel, modifié il y a 11 années.]

Hi,

I am owner of www.opensource-techblog.com. I wrote blog and give example of portlet written on liferay 6.1. I guess starting from liferay 6.2, liferay had mandate to provide portlet name space while accessing parameter from request. By default this behavior is enable. To disable you need to disable one flag in liferay-portlet.xml file.I don't remember exact attribute name but it should be something like "namespace". Set it false and then try run the code. Hope it should work.

Let me know if still you face the issues

Nilang
