[jira] Commented: (MYFACES-1156) Model update uses empty string instead of null. Custom String converter not possible.

Veit Guna commented on MYFACES-1156:
------------------------------------

Sorry, I forgot to mention, that using a custom String converter doesn't work.

--cut here--
        Class valueType = vb.getType(facesContext);
        if (valueType == null) return null;

        if (String.class.equals(valueType)) return null;    //No converter needed for String type
        if (Object.class.equals(valueType)) return null;    //There is no converter for Object class
--cut here--

> I've encountered a problem using String values with myfaces. The default behavior of myfaces (probably jsf?) seems to be, that Input values of type String
> get converted to an empty String (""). Instead I would like to have a null value updated in my model. This is because I don't want to have
> empty Strings in my DB - but nulls.
