Hi. I have some problems with one-to-many relationships:
When I use the xdoclet as below:
/**
* @hibernate.set
* lazy="true"
* @hibernate.collection-key
* column="team_id"
* @hibernate.collection-one-to-many class="test.Player"
*/
public Set getPlayers() {
return players;
}
It results in the following mapping file:
<set
role="players"
lazy="true"
readonly="false"
cascade="none"
sort="unsorted"
>

<key
column="team_id"
>
</key>

<one-to-many
class="test.Player"
/>

</set>

Which in its turn during runtime gives the following error:
net.sf.hibernate.PropertyNotFoundException: Could not find a getter for null in class com.infonatural.Team and a total failure to run the program.

However if i add a property name="players" to the set tag, it works during runtime, but gives the following ugly message at setup:
[ERROR] XMLHelper - -Error parsing XML: XML InputStream(37) <org.xml.sax.SAXParseException: Attribute "name" must be declared for element type "set".>org.xml.sax.SAXParseException: Attribute "name" must be declared for element type "set".
at org.apache.xerces.util.ErrorHandlerWrapper.createSAXParseException(Unknown Source)

Anything I am doing wrong? Should I worry about the second message? Everything does work..

Using Hibernate 2.03 by the way..

Make sure you are generating the code with XDoclet with the version 2 tag.

I will try that.. Quick Idea where I add that tag? Using xdoclet 1.2b3

The ANT task for XDoclet requres the version to be set to version 2 rather than no version as it will generate mappings for version 1.x of Hibernate, eg,

<hibernatedoclet
destdir="${generated.home}"
excludedtags="@version,@author,@todo"
force="${generated.forced}"
mergedir="${generated.home}"
verbose="false">

<hibernate version="2.0"/> <!-- HERE -->

<fileset dir="${src.home}">
<include name="**/hibernate/*.java"/>
</fileset>

<hibernate/>

</hibernatedoclet>


See above. Ill have to add it to the docs.

Opps had it in there twice. Should be:
<hibernatedoclet
destdir="${generated.home}"
excludedtags="@version,@author,@todo"
force="${generated.forced}"
mergedir="${generated.home}"
verbose="false">

<fileset dir="${src.home}">
<include name="**/hibernate/*.java"/>
</fileset>

<hibernate version="2.0"/>

</hibernatedoclet>

It was in the dicumentation though I have made it more obvious to the casual reader.

Thanks! That worked like a charm.
