Multi-table-entity insert before test

[xxlabaza]

Hi!

I have an Entity from two tables, like this one:

@Entity
@Table(name = "admin_goods_cat_soft")
@SecondaryTable(name = "c_categories",
                pkJoinColumns = @PrimaryKeyJoinColumn(name = "id",
                                                      referencedColumnName = "a_id"))
public class ProductSoftCategory implements Serializable {

    private static final long serialVersionUID = -1186100819002788670L;

    @Id
    @GeneratedValue
    @Column(name = "a_id")
    private Integer id;

    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "parent_id", table = "c_categories", referencedColumnName = "a_id")
    private ProductSoftCategory parent;

    @Column(name = "name", table = "c_categories")
    private String name;

    @Column(name = "a_alias")
    private String alias;

    // other fields from `admin_goods_cat_soft ` and `c_categories ` tables

The entity contains some columns from two tables, but not all of them.

DbUnit schema has description of these tables:

<!ELEMENT c_categories EMPTY>
<!ATTLIST c_categories
    id CDATA #REQUIRED
    parent_id CDATA #IMPLIED
    template_id CDATA #IMPLIED
    key_id CDATA #IMPLIED
    enum_value_id CDATA #IMPLIED
    name CDATA #REQUIRED
    alias CDATA #IMPLIED
    image_url CDATA #IMPLIED
    level CDATA #REQUIRED
    sort CDATA #IMPLIED
    discount_category_id CDATA #IMPLIED
    dont_use_in_search CDATA #IMPLIED
    is_hidden CDATA #IMPLIED
>
<!ELEMENT admin_goods_cat_soft EMPTY>
<!ATTLIST admin_goods_cat_soft
    a_id CDATA #REQUIRED
    a_alias CDATA #REQUIRED
    title CDATA #IMPLIED
    description CDATA #IMPLIED
    image_url CDATA #IMPLIED
    dont_show_children CDATA #IMPLIED
    model_grouping_keys CDATA #IMPLIED
    external_link CDATA #IMPLIED
    show_in_tree CDATA #IMPLIED
    cat_model_grouping_keys CDATA #IMPLIED
    mxp_description CDATA #IMPLIED
    is_new CDATA #IMPLIED
>

Before some test class I try to write the values in database by DbUnit:

<c_categories id="1"
              name="Root"/>

<admin_goods_cat_soft a_id="1"
                      a_alias="root"
                      title="Root category"/>

... but test fails down at this step with the following exception:

org.dbunit.dataset.NoSuchColumnException: c_categories.TEMPLATE_ID -  (Non-uppercase input column: template_id) in ColumnNameToIndexes cache map. Note that the map's column names are NOT case sensitive.

It's strange, because I don't event use a c_categories.TEMPLATE_ID column in my Entity. Please, help me to solve this bug, because it stops my work for two days...

P.S. sorry for my English, it's not my native language
