Hey Juan!
I found the culprit. There is a missing key in the editorMap in the archetype's applicationContext.xml Here it is: <entry> <key> <value> supportsExtension('org.trails.descriptor.annotation.PossibleValuesDescriptorExtension') or supportsExtension('org.trails.descriptor.annotation.InitialValueDescriptorExtension') </value> </key> <bean class="org.apache.tapestry.util.ComponentAddress"> <constructor-arg index="0"> <value>trails:Editors</value> </constructor-arg> <constructor-arg index="1"> <value>filteredAssociation</value> </constructor-arg> </bean> </entry> You need that entry in place to make @PosibleValues work. About the mapping thing: * @ManyToOne and @Transient are incompatibles * "mappedBy" properties are readonly, you will need some extra code to make them "editable" * It's best to use the Collection's inverse property together with the mappedBy * If Provincia is a "child" collection (aka: composition) region & pais properties should be readonly, there is no point in using the @PosibleValues there. If you want to use @PosibleValues Provincia shouldn't be marked as "child" collection. I'm sending you two mapping examples one with Provincia as a composition and the other one with Provincia as an aggregation. I hope it helps. Saludos. Alejandro.
