Paul,
You can replace the original DataSqueezer service by your own implementation,
which will register your custom squeeze adaptor.
public class MyDataSqueezerImpl extends
org.apache.tapestry.util.io.DataSqueezerImpl {
public MyDataSqueezerImpl(ClassResolver resolver) {
super(resolver);
new CustomSqueezeAdaptor().register(this);
}
}
Then in your hivemodule.xml:
<module>
<!-- Replacement for the DataSqueezer service -->
<implementation service-id="tapestry.data.DataSqueezer">
<invoke-factory>
<construct class="com.acme.MyDataSqueezerImpl">
<class-resolver/>
</construct>
</invoke-factory>
</implementation>
</module>
No need to register your custom squeeze adaptor in your pages anymore.
Hope this helps,
Raphael
