I'm trying to insert records to the DB and fails due to a many-to-one relation:

[b]Hibernate mapping[/b]

<class name="com.bevents.infra.common.metadata.GeneralMeasureStatData" table="GENERAL_MEASURE_STATS">

did anyone use it successfully[b][/b]

sorry, i gave the wrong mapping - (the problem was not solved)

<class name="com.bevents.infra.common.metadata.GeneralMeasureStatData" table="GENERAL_MEASURE_STATS">
<id name="id" column="ID">
<generator class="assigned"/>
</id>
<many-to-one name="measureStatTypeId"-->
column="MEASURE_STATS_TYPE_ID"-->
update="true" insert="true" not-null="true"--> class="com.bevents.infra.common.metadata.MeasureStatTypeData" />
<property name="description" column="DESCRIPTION" length="50"/>
<property name="columnName" column="COLUMN_NAME" length="50"/>
<property name="isPercent" column="IS_PERCENT" not-null="true"/>
<property name="engineName" column="ENGINE_NAME" length="50"/>
</class>

Post the code of your POJOs (GeneralMeasureStatData, MeasureStatTypeData) as well as the code in which you try to insert the records.

Best regards

i'm not sending the AbstractDataObject since it is only implementing a reflection toString()...

[code]

}
[/code]

[code]/**

public class GeneralMeasureStatData extends MeasureAttributeStatData{

public GeneralMeasureStatData() {
}

public GeneralMeasureStatData(int id, int measureStatTypeId, String description, String columnName, boolean isPercent, String engineName) {
super(id, 0, measureStatTypeId, description, columnName, isPercent, false, engineName);
}

}
[/code]

I don't see a class MeasureStatTypeData in the code you posted. There must be something wrong with its getter of id (see your exception).
