I am trying to update the portlet preferences within my code, but the preferences are not being persisted. I have based my code on what I found in the WeatherPortlet. I even added debugging to the WeatherPortlet to see how it was doing things. Here is the code:

public void processAction(ActionRequest request, ActionResponse response) throws PortletException {
 String newZip = request.getParameter("newzip");
 log.debug("newZip=" + newZip);
 if(null != newZip) {
 PortletPreferences prefs = request.getPreferences();
 try {
 prefs.setValue("RssXml", RSS_URL_PREFIX + newZip);
 prefs.store();
 String xxx = prefs.getValue("RssXml", null);
 log.debug("RssXml=" + xxx);
 } catch(Exception e) {
 e.printStackTrace();
 }
 }
 response.setRenderParameter("newzip", RSS_URL_PREFIX + newZip);
 response.setPortletMode(PortletMode.VIEW);
}

And here is what shows up on the log file (sans leading junk):

newZip=92691
RssXml=http://xml.weather.yahoo.com/forecastrss?p=33145

The 33145 zip is what is configured in portal.xml. So immediately after setting the preference and storing it, it disappears and reverts back to the original setting.

Should I open a JIRA issue?

Using: JBoss 4.0.4-GA, JBoss Portal 2.4.0-CR1, JDK 5.0

Standard disclaimer: I searched through the forum, JIRA, and even did a general google and could not find anything on this topic.
