Empty ClientPreferences in ClientSession.execLoadSession after logout and re-login [message #1800030]

Hello.

I have this problem:

I have execLoadSession in ClientSession class:

public class ClientSession extends AbstractClientSession {
...
	@Override
	protected void execLoadSession() {
		// pre-load all known code types
		CODES.getAllCodeTypes("cz.gpe.per.portal.app.shared");

		// The locale needs to be set before the Desktop is created.
	    String localeString = ClientUIPreferences.getClientPreferences(ClientSession.get()).get(PREF_USER_LOCALE, null);
	    LOG.info("localeString: " + (localeString == null ? "!!! NULL !!!" : localeString));
	    if (localeString != null) {
	      Locale userLocale = LocaleUtility.parse(localeString);
	      setLocale(userLocale);
	    }
	    
		setDesktop(new Desktop());
	
	}

If I login after server restart, "localeString" contains right value (i.e. "cs_CZ" or "en_US"), but if I logout and then login again (without server restart), then "localeString" is null (ClientPreferences has no elements).

Could someone advise me?
Thank you.

Addition:

CientSesion.get() is null in this situation (login again after logout without server restart).

It seems that execLoadSession is called before ClientSession is initialized. But after server restart is that called after ClientSession initialize.

Where do I make a mistake, please? Thanx.

Hi Miloslav

I have not tested it, just guessing: Does it make a difference if you use the current instance (this) instead ClientSession.get()?

Thank you for your interest, but my problem solved adding line:
initializeSharedVariables();

public class ClientSession extends AbstractClientSession {
...
	@Override
	protected void execLoadSession() {
		// pre-load all known code types
		CODES.getAllCodeTypes("cz.gpe.per.portal.app.shared");

		initializeSharedVariables();		// <<< THIS SOLVED MY PROBLEM

		// The locale needs to be set before the Desktop is created.
	    String localeString = ClientUIPreferences.getClientPreferences(ClientSession.get()).get(PREF_USER_LOCALE, null);
	    LOG.info("localeString: " + (localeString == null ? "!!! NULL !!!" : localeString));
	    if (localeString != null) {
	      Locale userLocale = LocaleUtility.parse(localeString);
	      setLocale(userLocale);
	    }
	    
		setDesktop(new Desktop());
	
	}
