    how to change Portlet Preferences

    Giuseppe Martino Newbie

      Hello
      I create a portlet with a preference in portlet.xml, and deploy it successfully on JBoss Portlet Container.
      The xml for this porlet is following:


      <portlet>
       <description>PreferencesPortlet</description>
       <portlet-name>PreferencesPortlet</portlet-name>
       <display-name>PreferencesPortlet</display-name>
       <portlet-class>it.portlet.PreferencesPortlet</portlet-class>
       <expiration-cache>0</expiration-cache>
       <supports>
       <mime-type>text/html</mime-type>
       <portlet-mode>VIEW</portlet-mode>
       <portlet-mode>EDIT</portlet-mode>
       </supports>
       <portlet-preferences>
       <preference>
       <name>userName</name>
       <value>Mark</value>
       <read-only>false</read-only>
       </preference>
       <preferences-validator>it.validator.UserNameValidator</preferences-validator>
       </portlet-preferences>
       <portlet-info>
       <title>Portlet Preferences</title>
       <short-title>PreferencesPortlet</short-title>
       </portlet-info>
       </portlet>
      


      It works fine but when i change the value of preference value in xml it does not reflect it, I try to modify the preference in runtime but when i read the value of the preference in runtime it always show old value. I know that i can edit this value using protlet api, using setValue() method and store() method, but I want know why this doesn't work in my portlet.


      Thanks in advance
