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.
