Re: [cdt-dev] Codan launch modes 
I'm using Eclipse 4.6.3, targetting Mars.2 (4.5.2)

Are the problems you tune "codan standard" or customs?

My Codan "problem" are custom, I've defined them in plug-in.xml
I wish declare in XML the launch modes but extensions points doesn't allow declaring launch modes, API are a workaround for me. 

Here is my code:

   @Override
   public void initPreferences( IProblemWorkingCopy problem ) {
       super.initPreferences( problem );
       final RootProblemPreference pp = (RootProblemPreference)problem.getPreference();        final LaunchModeProblemPreference lmpp = pp.getLaunchModePreference(); 
       lmpp.setRunningMode( CheckerLaunchMode.RUN_ON_FULL_BUILD, false );
       lmpp.setRunningMode( CheckerLaunchMode.RUN_ON_INC_BUILD , false );
       lmpp.setRunningMode( CheckerLaunchMode.RUN_ON_DEMAND    , true  );
       lmpp.setRunningMode( CheckerLaunchMode.RUN_ON_FILE_OPEN , false );
       lmpp.setRunningMode( CheckerLaunchMode.RUN_AS_YOU_TYPE  , true  );
       lmpp.setRunningMode( CheckerLaunchMode.RUN_ON_FILE_SAVE , false );
       final SuppressionCommentProblemPreference scp = pp.getSuppressionCommentPreference(); 
       scp.setValue( "//[[derogations(" + problem.getName() + ")]]" );
       System.out.println( problem.getName() + ": " + problem.getPreference()); 
   }
When it runs the log is correct but the UI doesn't show these settings, but the default and parsing is made when I open a file.

And the suppression comment is empty.

    setLaunchModes isn't a method of LaunchModeProblemPreference
    (codan 4.0.0)

    Would you say setRunningMode?

    With setRunningMode, results are the same: behaviour and preferences
    page are different than settings modified via API.

    It seems only the persistence of user settings - set via UI - is
    taken
    in account.

    API has no effect.
