Hello Werner,
thanks a lot for your reply!
Here is the mapping as I am using it right now:
<mapping>
<class name="ab.Data">
<map-to xml="data"/>
<field name="data" type="ab.A" collection="array">
<bind-xml name="a" node="element"/>
</field>
</class>
<class name="ab.A">
<field name="field" type="ab.B" container="true" collection="array">
<bind-xml name="value" node="element"/>
</field>
</class>
<class name="ab.B">
<field name="value" type="integer"/>
</class>
</mapping>
and this is the result generated by Castor:
<data>
<a>
<value>15</value>
<value>8</value>
</a>
<a>
<value>12</value>
<value>17</value>
<value>8</value>
<value>3</value>
</a>
</data>
this is as far as I got, and it's already very beautiful. But the crucial
step is to get the "id" field of the B type into the "id" attribute of the
<a> element like in
<data>
<a id="series1">
<value>15</value>
<value>8</value>
</a>
<a id="series2">
<value>12</value>
<value>17</value>
<value>8</value>
<value>3</value>
</a>
</data>
I'm very grateful for any help here!
best regards, Georg
I've added the sources of the java types, maybe it's of any help ...
