Hi,
This try failed, I got the same error message:
org.apache.torque.TorqueException: You must specify KeyDef attributes
for this TableDataSet in order to delete a Record.
I added the code, which is bold, in the XML-Schema file:
<table name="sys_contact_category2sys_contact"
javaName="SYSContactCategory2SYSContact">
<column name="sys_contact_id" *primaryKey="true"
*required="true" type="BIGINT"/>
<column name="sys_contact_category_id"* primaryKey="true"*
required="true" type="INTEGER"/>
<foreign-key foreignTable="sys_contact">
<reference foreign="id" local="sys_contact_id"/>
</foreign-key>
<foreign-key foreignTable="sys_contact_category">
<reference foreign="id" local="sys_contact_category_id"/>
</foreign-key>
</table>
The peer classes were successfully created, but the problem was not
solved. Did I do anything wrong with the XML-Schema?
Thanks
Guo
