Thank you Ollie.
My problem is that "Message text..." is not within it's own tags. So I
can not define a field with a ame "string":
<field name="string" type="string">
<sql name="string" type="varchar" />
<bind-xml name="string" node="element" />
</field>
Is the any solution for that?
<message flag=1> Message1 text........ </message>
About the version: It is me who is missing something. Does version 1.0
sounds right?
Thanks again.

Hi Tanya !
If the messageHolder can have multiple messages, but a message
is hold exclusively by one messageHolder then that relation is
a so called one-many-relation.
The mapping might look like:
....
<class name="message" identity="id" key-generator="keygen">
<map to table="messages" />
<field name="Id" type="integer">
<sql name="id" type="integer" />
<bind-xml name="Id" node="attribute"/>
</field>
<field name="flag" type="integer">
<sql name="flag" type="integer" />
<bind-xml name="flag" type="attribute" />
</field>
<field name="string" type="string">
<sql name="string" type="varchar" />
<bind-xml name="string" node="element" />
</field>
<!-- now the relation -->
<field name="messageHolder" type="messageHolder">
<sql name="messageHolder_id" type="integer" />
<bind-xml name="mh" node="attribute" />
</field>
</class>
<class name="messageHolder" identity="id" key-generator="keygen">
<map to table="messageHolder" />
<field name="Id" type="integer">
<sql name="id" type="integer" />
<bind-xml name="Id" node="attribute" />
</field>
<field name="message" type="message" required="false" collection
="vector">
<sql many-key="messageHolder_id" />
<bind-xml name="messages" node="element" />
</field>
</class>
....
This would lead you to the following xml:
<messageHolder id="1">
<message id="2" mh="1" flag="1">
<string>Message1 text...........</string>
</message>
<message id="3" mh="1" flag="1">
<string>Message2 text...........</string>
</message>
</messageHolder>
If you really need to have the mentioned structure then maybe you want to
have
a Vector containing messages in the messageHolder class.
But I would suggest to use a xml-structure like:
<messageHolder>
<message flag="1" text="Message1" />
<message flag="2" text="Message2" />
</messageHolder>
which could be produced by the upper mapping by changing the node attribute
for
the text to attribute instead of element.
I hope that I got the point :) And by the way I've never heard of
castor version 1.2 though I would be glad :) Am I missing something ?
bye Ollie
