    Hi,

    When I have a inherited getter in the domain object and the
    corresponding attribute appears in an inline parameter map, I get a
    NullPointerException:

Caused by: com.ibatis.common.jdbc.exception.NestedSQLException: --- The error occurred in Evento.abator.sqlmap.xml. --- The error

    occurred while applying a parameter map.  --- Check the
    Evento.abatorgenerated_updateByPrimaryKey-InlineParameterMap.  ---

    Here is BasicParameterMap.java:165:

      // Set Parameter
      TypeHandler typeHandler = mapping.getTypeHandler();
      if (value != null) {
    =>    typeHandler.setParameter(ps, i + 1, value,
    mapping.getJdbcTypeName()); // <= typeHandler == null !
      } else if (typeHandler instanceof CustomTypeHandler) {
        typeHandler.setParameter(ps, i + 1, value,
    mapping.getJdbcTypeName());
      } else {

    When I overwrite the getter in the subclass, the error disappears.
    Maybe iBatis can't get the return type of inherited methods and, as
    a result, can't resolve the type handler?
