Hi Srikanth
Sorry for being late but i was busy on other activities....
Anyway we did some debug and, at least on LF 4.4.2, we found in class com.liferay.portal.service.impl.PortletPreferencesLocalServiceImpl the following method


	public javax.portlet.PortletPreferences getPreferences(
			long companyId, long ownerId, int ownerType, long plid,
			String portletId, String defaultPreferences)
		throws PortalException, SystemException {

		Map prefsPool = PortletPreferencesLocalUtil.getPreferencesPool(
			ownerId, ownerType);

		String key = encodeKey(plid, portletId);

		PortletPreferencesImpl prefs =
			(PortletPreferencesImpl)prefsPool.get(key);

		if (prefs == null) {
			PortletPreferences portletPreferences = null;

			Portlet portlet = portletLocalService.getPortletById(
				companyId, portletId);

			try {
				portletPreferences =
					portletPreferencesPersistence.findByO_O_P_P(
						ownerId, ownerType, plid, portletId);
			}
			catch (NoSuchPortletPreferencesException nsppe) {
				System.out.println("NoSuchPortletPreferencesException");
				nsppe.printStackTrace();
				System.out.println("-------------------- fine stack ----------------------------------------");
				[color=#FA1010]long portletPreferencesId = counterLocalService.increment();

				portletPreferences = portletPreferencesPersistence.create(
					portletPreferencesId);

				portletPreferences.setOwnerId(ownerId);
				portletPreferences.setOwnerType(ownerType);
				portletPreferences.setPlid(plid);
				portletPreferences.setPortletId(portletId);

				if (Validator.isNull(defaultPreferences)) {
					if (portlet == null) {
						defaultPreferences = PortletImpl.DEFAULT_PREFERENCES;
					}
					else {
						defaultPreferences = portlet.getDefaultPreferences();
					}
				}

				portletPreferences.setPreferences(defaultPreferences);

				portletPreferencesPersistence.update(portletPreferences);
			}

			prefs = PortletPreferencesSerializer.fromXML(
				companyId, ownerId, ownerType, plid, portletId,
				portletPreferences.getPreferences());

			prefsPool.put(key, prefs);[/color]
		}

		return (PortletPreferencesImpl)prefs.clone();
	}

As you can see in the red block if something is wrong in recovering the portlet preferences the default preferencies are loaded, with no log message. We think this could be the problem. I don't know if this can be usefull for you too
We are going on in debuging

Hi Angelo,

I am using liferay tomcat 5.2.3 and sdk of the same version.

When i deploy the portlet onto my local server, the preferences are getting lost from there.

I am ending up with entering again the values there. Please let me know if you have any solution for this issue. Thanks.

Srik

Hi all

I'm using this environment:

Liferay 4.4.2
Spring 2.0.6
MySQL (and once also on Postgress)

It's happening a very very strain thing
I built some portlet pages where i added some instances of my own spring based portlets
All worked pretty good
After some time (several month) i saw that all my spring portlets in the most of the pages lost their preferences. I reconfigured all the portlets and 2 days later i saw that they lost their preferences once again
I checked liferay DB and i didn't find the portlets preferences in the DB.
How can i solve the issue? What should i check to fix and solve it?

Regards,
Angelo
