<eStructuralFeatures xsi:type="ecore:EReference" name="value"

</eClassifiers>
and the referencing class:
<eClassifiers xsi:type="ecore:EClass" name="ToolElement">
<eStructuralFeatures xsi:type="ecore:EReference" name="inputPins"
upperBound="-1"
eType="#//IntegerToToolPinMapEntry" containment="true"/>
</eClassifiers>

Hi Luzi,
For my info, can you also post the relevant part of the mapping? And the stack trace of the
mappingexception?

discriminator-value="ToolElement" table="`toolelement`">
<meta attribute="eclassName">ToolElement</meta>
<meta attribute="epackage">http:///xxxxxxxxxxxxxx.ecore</meta>
<map name="inputPins" lazy="true" cascade="all,delete-orphan">
<key update="true" foreign-key="toolelement_inputpins">
<column name="`toolelement_inputpins_e_id`" not-null="false"
unique="false"/>
</key>
<map-key type="java.lang.Integer"/>
<one-to-many entity-name="ToolPin"/>
</map>
</class>
