[dvayanu]

Currently this method is

	public void swapLocalizationsElement(int index1, int index2){
		String tmp1, tmp2;
		tmp1 = ((StringProperty)getList(PROP_LOCALIZATIONS).get(index1)).getString();
		tmp2 = ((StringProperty)getList(PROP_LOCALIZATIONS).get(index2)).getString();
		((StringProperty)getList(PROP_LOCALIZATIONS).get(index1)).setString(tmp2);
		((StringProperty)getList(PROP_LOCALIZATIONS).get(index2)).setString(tmp1);
	} //method

generated into every class and element. Instead the content of this method can be generalized.

	public void swapLocalizationsElement(int index1, int index2){
           swapListElement(PROP_LOCALIZATIONS, index1, index1);
        }
