Bug found in Method protected HashMap toColumnValues(SqlDynaProperty[] properties, DynaBean

Description: exception will thrown in the case of tables with composite primary keys and the
pk columns are in different types. 

Use case throw exception: Table 'Employee' has a composite primary key with the combination
of two columns: {int: emplyeeid, string LastName}. 
                                        Exception may thrown because of the keyset and values
stored in Hashmap may disordered and give the value of "LastName" to the key of "emplyid";

Reason: Hashmap is used at here for storage and the items stored in Hashmap are not sorted

     * Derives the column values for the given dyna properties from the dyna bean.
     * @param properties The properties
     * @param bean       The bean
     * @return The values indexed by the column names
    protected HashMap toColumnValues(SqlDynaProperty[] properties, DynaBean bean)
        HashMap result = new HashMap();

        for (int idx = 0; idx < properties.length; idx++)
                       bean == null ? null : bean.get(properties[idx].getName()));
        return result;
