Hello Joachim, thanks for your answer. I tried to change mapping in this manner:
[CareGiver mapping, complete inheritancetree changed]
<field name="id" type="java.lang.Integer">
<sql name="ID" type="integer"/> <--- defining SQLType
<bind-xml name="id" node="element"/>
</field>
ClassCastException occurs as before. At this time, i believe this is a
bug and no error in my own layer 8.
I cant figure out why castor fail at this object.
