Sorry Nick! that was a copy-and-paste mistake. The cell depends on
Sector but it does not work. Here is my real xml file based on the
folowing model:
Eeprom 1--------------------* EepromBlock 1--------------------*
<class name="EepromCell" identity="id" key-generator="IDENTITY"
depends="EepromBlock">
<map-to table="eepromcell"/>
<field name="id" type="integer">
<sql name="id" type="integer"/>
</field>
<field name="name" type="string" required="true"
transient="false"
direct="false">
<sql name="name" type="char"/>
</field>
<field name="value" type="string" required="true"
transient="false"
direct="false">
<sql name="value" type="char"/>
</field>
<!-- reference to the parent -->
<field name="eepromBlock" type="EepromBlock"
required="true"
transient="false" direct="false">
<sql name="EepromBlock_Id"/>
</field>
</class>
<class name="EepromBlock" identity="id" key-generator="IDENTITY"
depends="Eeprom">
<map-to table="eepromblock"/>
<field name="id" type="integer">
<sql name="id" type="integer"/>
</field>
<field name="number" type="integer">
<sql name="number" type="integer"/>
</field>
<!-- reference to the parent -->
<field name="eeprom" type="Eeprom" required="true"
transient="false"
direct="false">
<sql name="Eeprom_Id"/>
</field>
<!-- reference to the children-->
<field name="eepromCell" type="EepromCell"
collection="array"
required="true">
<sql many-key="EepromBlock_id"/>
</field>
</class>
<class name="Eeprom" identity="id" key-generator="IDENTITY">
<map-to table="eeprom"/>
<field name="id" type="integer">
<sql name="id" type="integer"/>
</field>
<!-- reference to the children-->
<field name="eepromBlock"
type="EepromBlock" collection="array"
required="true">
<sql many-key="Eeprom_id"/>
</field>
</class>
