PropertyInferredData fails on generic entities ---------------------------------------------- Key: ANN-181 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-181 Project: Hibernate Annotations Type: Bug

Components: binder Versions: 3.1beta7 Reporter: Ryan Dewell Assignee: Paolo "Nusco" Perrotta Fix For: 3.2.0

Exception is thrown by PropertyInferredData at extractType when handling a generically typed entity. This problem did not exist in previous versions of PropertyInferredData where "method.getReturnType()" was used to extract the type instead. Workaround patch (falls back to original procedure): -------------------------------- try { returnedClass = extractType(type); } catch (Exception e){ returnedClass = method.getReturnType(); } Example generic entity: -------------------------------- package com.brightmarket.core.workflow; import javax.persistence.Column; import javax.persistence.Entity; import javax.persistence.Table; import org.hibernate.annotations.Type; import org.hibernate.validator.NotNull; import com.brightmarket.core.Model; @Entity(name="LifecycleHistory") @Table(name="workflow_lifecycle_history") public class LifecycleHistory<STATE extends Enum, REASON extends Enum> extends Model{ private static final long serialVersionUID = -8445979354786791933L; private STATE previousLifecycle; private STATE newLifecycle; private REASON newLifecycleReason; @Column(name="new_lifecycle") @NotNull @Type(type="StringEnum") public STATE getNewLifecycle() { return newLifecycle; } public void setNewLifecycle(STATE lifecycle) { this.newLifecycle = lifecycle; } @Column(name="new_lifecycle_reason") @Type(type="StringEnum") public REASON getNewLifecycleReason() { return newLifecycleReason; } public void setNewLifecycleReason(REASON lifecycle) { this.newLifecycleReason = lifecycle; } // NOTE: this isn't strictly needed because it should be accessible via the date stamped lifecycle history occuring prior to this entry. @Column(name="previous_lifecycle") @Type(type="StringEnum") public STATE getPreviousLifecycle() { return previousLifecycle; } public void setPreviousLifecycle(STATE previousLifecycle) { this.previousLifecycle = previousLifecycle; } }
