      Description

      When using multivalued field (with multiple default values separated by spaces), and using the field with the Document > DocumentMultivaluedProperty.addItem API, one gets a NullPointerException with the following stack trace:

      The goal for this ticket is to fix the NPE and to have the API working with all types of scalar data offered by Nuxeo (including integer, date...)

      Currently it works only with String and Boolean because the newInstance method is defined for StringType and BooleanType classes
