I'm refining down the trouble I mentioned in another thread.

The first mapping below works fine. The second mapping fails. Note the only different is that "ValueObject" has a simple map added to it. Can anyone explain why this fails?

Quote:
Schema text failed: Problem trying to set property
type by reflection: Could not find a getter for stuff in class ValueObject


This mapping works fine:
Code:

    <class name="KeyObject" table="ko">
        <id name="id" type="string" unsaved-value="null" >
            <column name="id" sql-type="char(32)" not-null="true"/>
            <generator class="uuid.hex"/>
        </id>
        <property name="name" type="string" not-null="true"/>
        <property name="someField" type="string" not-null="true"/>

    </class>

    <class name="ValueObject" table="vo">
        <id name="id" type="string" unsaved-value="null" >
            <column name="id" sql-type="char(32)" not-null="true"/>
            <generator class="uuid.hex"/>
        </id>
        <property name="name" type="string" not-null="true"/>
        <property name="someOtherField" type="string" not-null="true"/>
    </class>

    <class name="MapClass" table="mc">
        <id name="id" type="string" unsaved-value="null" >
            <column name="id" sql-type="char(32)" not-null="true"/>
            <generator class="uuid.hex"/>
        </id>
        <map name="kvMapping" lazy="true" >
            <key column="id"/>
            <composite-index class="KeyObject" >
                <key-property name="name"/>
                <key-property name="someField"/>
            </composite-index>
            <composite-element class="ValueObject" />

        </map>

        <property name="name" type="string" not-null="true"/>
        <property name="someOtherField" type="string" not-null="true"/>
    </class>


2nd mapping, fails:

Code:
    <class name="KeyObject" table="ko">
        <id name="id" type="string" unsaved-value="null" >
            <column name="id" sql-type="char(32)" not-null="true"/>
            <generator class="uuid.hex"/>
        </id>
        <property name="name" type="string" not-null="true"/>
        <property name="someField" type="string" not-null="true"/>

    </class>

    <class name="ValueObject" table="vo">
        <id name="id" type="string" unsaved-value="null" >
            <column name="id" sql-type="char(32)" not-null="true"/>
            <generator class="uuid.hex"/>
        </id>
        <property name="name" type="string" not-null="true"/>
        <property name="someOtherField" type="string" not-null="true"/>
        <map name="stuff" lazy="true" >
            <key column="id"/>
            <index column="key" type="string"/>
            <element column="value" type="string"/>
        </map>
    </class>

    <class name="MapClass" table="mc">
        <id name="id" type="string" unsaved-value="null" >
            <column name="id" sql-type="char(32)" not-null="true"/>
            <generator class="uuid.hex"/>
        </id>
        <map name="kvMapping" lazy="true" >
            <key column="id"/>
            <composite-index class="KeyObject" >
                <key-property name="name"/>
                <key-property name="someField"/>
            </composite-index>
            <composite-element class="ValueObject" />

        </map>

        <property name="name" type="string" not-null="true"/>
        <property name="someOtherField" type="string" not-null="true"/>
    </class>

Does your ValueObject class have a method defined as
Code:
public java.util.Map getStuff() { ... }

I'm using hbm2java. Hibernate is creating the java object ValueObject. Perhaps hibernate is not making that method?

Looking at the generated code, ValueObject does not have the getter. In fact, it has no fields in it. If I comment out MapClass entirely, all the fields in ValueObject show up as expected. (with the right getters/setters)

So I guess what is happening is the <composite-element> in MapClass' kvMapping is creating a whole new class called ValueObject which overwrites the real ValueObject.

So then: How do I get the element in MapClass' kvMapping to point at the (real) ValueObject type? What am I doing wrong?
