Error: COntent is not available. (when using tags)
I'm pretty new at portlet creation, but ive managed to develop and deploy simple portlets that only require the view or the help pages. I am trying now to creat a portlet where i could change one of the preferences from my edit.jsp. My problem is that whenever i include a tag like : <portlet:defineObjects/> .I get Error: Content is not available.
My log file produces the following:

my code is as follows:
<%@page contentType="text/html"%>
<%@page pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/portlet" prefix="portlet" %>
<%@ page session="false" %>
<%@ page import="javax.portlet.*" %>
<%@ page import="java.util.*" %>
<portlet:defineObjects/>
<b>HelloWorld - EDIT MODE</b>
<form method="POST" action='<portlet:actionURL />'>
<table>
<tr>
<td>city</td><td><input name="city"value="city"/>/></td>
</tr>
<tr>
<td></td>
<td><input type="submit" value="Submit"/></td>
</tr>
</table>
</form>
