[Hibernate-JIRA] Created: (ANN-526) Property xyz has an unbound type - is that so?

by Sebastian Kirsch (JIRA)

Property xyz has an unbound type - is that so? ---------------------------------------------- Key: ANN-526 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-526 Project: Hibernate Annotations Type: Bug Versions: 3.2.1 Reporter: Sebastian Kirsch Priority: Minor Attachments: Hibernate ANN-526.zip I get this "Property reference has an unbound type and no explictit target entity" exception and I think this is not exactly true. I'm not sure if this is a bug or a feature requests though. Have a look at the attached files and read on. I guess the model ist pretty easy to understand. The AbstractGeneric allows my to have concrete entities referring to specifc other subclasses - as seen in ConcreteOther and ConcreteSelf. The test case "workingClasses" shows us that Hibernate may work with this model - note that the class AbstractGeneric itslef was NOT added to the configuration. Now for the problem: The class OtherEntity is a completly different entity, but it refers to instances of AbstractGeneric - to any subclass of it actually, as AbstractGeneric is obviously abstract. If you run the test case "otherClass" the first part states that Hibernate doesn't know AbstractGeneric - which is fine, so I add that class to the configuration and try to build a session factory again. Now we receive the beforementioned exception. That's the situation. So is AbstractGeneric really an unbound type? I'd say it is not - T has an upper bound which should be good enough to work with - we know the table and the PK... -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira

[Hibernate-JIRA] Created: (ANN-539) Generics and @Embedded doesn't work

by Christophe Vanfleteren (JIRA)

Generics and @Embedded doesn't work ----------------------------------- Key: ANN-539 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-539 Project: Hibernate Annotations Type: Bug Versions: 3.2.1 Environment: Hibernate 3.2.1, Oracle 10XE Reporter: Christophe Vanfleteren Attachments: generic.zip It doesn't seem to be possible to use a plain generic field as a component, for example: @Embedded private Range<Integer> bounds doesn't work (you get an "org.hibernate.AnnotationException: Property generic.GenericRange.min has an unbound type and no explicit target entity. Resolve this Generic usage issue or set an explicit target attribute (eg @OneToMany(target=) or use an explicit @Type") error. It does work when you extend the generic class in which you define the type (IntegerRange extends Range<Integer>) for example: @Embedded private IntegerRange bounds works I've attached some classes that demeonstrate this problem. This issue was raised before in http://opensource.atlassian.com/projects/hibernate/browse/ANN-406?page=co..., but was rejected since no testcase was provided. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira

[Hibernate-JIRA] Created: (ANN-506) Request for Expression Language (EL) for Validator annotations

by Chris Hansen (JIRA)

Request for Expression Language (EL) for Validator annotations -------------------------------------------------------------- Key: ANN-506 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-506 Project: Hibernate Annotations Type: New Feature Components: validator Environment: All Reporter: Chris Hansen Since annotations are limited to primitive types, I would like to see a type of EL for the Validator annotations (similar to the JSF/JSP EL). This would effectively overcome this limitation of annotations and allow for very powerful functionality, such as utilizing the natural ordering of classes. For example: @Range(min="#{MyClass.MIN_OBJECT}", max="#{MyClass.MAX_OBJECT}") public MyClass getCurrent() Assuming MIN_OBJECT and MAX_OBJECT are (static, final) instances of MyClass and MyClass implements Comparable<myClass>, the validator could compare the return value of the method with both MIN_OBJECT and MAX_OBJECT and validate that it is within the desired range. This is just an example. I'm sure there are many more interesting uses possible because this is a powerful concept. The regular functionality of the annotatinos could be preserved by treating static (non-EL) values, such as the string "0", as old-style primitives, e.g. @Min(value="0"). -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira

[Hibernate-JIRA] Created: (ANN-434) Confusing error message with @EmbeddedId and @Id

by Patrick Moore (JIRA)

Confusing error message with @EmbeddedId and @Id ------------------------------------------------ Key: ANN-434 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-434 Project: Hibernate Annotations Type: Bug Versions: 3.2.0.cr1 Environment: Hibernate 3.2.0.cr2 Reporter: Patrick Moore trying to create an entity with embeddedid and automatically generated ids. The resulting error message was very confusing and may be a bug as well. (See below for sample files) Notice the message is that TransPolId doesn't have an @Id property when in fact it does. The problem is 'solved' by removing the @Id in the TransPolId class. This caused a lot of wasted time on my part please fix for the next person! -------------------------------------------------------------------------------- Some additional debugging notes: The problem is caused in part because when expanding TransPolId to within AnnotationBinder.processElementAnnotations() isIdentifierMapper == false so none of the checks looking for this sort of thing execute. I believe the solution is to change AnnotationBinder.bindId() as follows: (original): if ( isComposite ) { id = fillComponent( propertyHolder, inferredData, isPropertyAnnotated, propertyAccessor, false, entityBinder, isEmbedded, isIdentifierMapper, mappings ); Component componentId = (Component) id; componentId.setKey( true ); if ( componentId.getPropertySpan() == 0 ) { throw new AnnotationException( componentId.getComponentClassName() + " has no persistent id property" ); } } (changed): if ( isComposite ) { id = fillComponent( propertyHolder, inferredData, isPropertyAnnotated, propertyAccessor, false, entityBinder, isEmbedded, true, mappings <<<<<<<<<<<<<<< isIdentifierMapper replaced by true ); Component componentId = (Component) id; componentId.setKey( true ); if ( componentId.getPropertySpan() == 0 ) { throw new AnnotationException( componentId.getComponentClassName() + " has no persistent id property" ); } } Output: java.vm.name=Java HotSpot(TM) Client VM, cache.provider_class=org.hibernate.cache.NoCacheProvider, file.encoding=Cp1252, java.specification.version=1.5, hibernate.show_sql=true, hibernate.connection.pool_size=1} 16:19:01,109 DEBUG [Configuration] Preparing to build session factory with filters : {} 16:19:01,109 DEBUG [AnnotationConfiguration] Execute first pass mapping processing 16:19:01,109 DEBUG [AnnotationConfiguration] Process hbm files 16:19:01,109 DEBUG [AnnotationConfiguration] Process annotated classes 16:19:01,125 INFO [AnnotationBinder] Binding entity from annotated class: com.transparentpolitics.core.persistence.IdUsing1 16:19:01,125 DEBUG [Ejb3Column] Binding column DTYPE unique false 16:19:01,125 DEBUG [EntityBinder] Import with entity name=IdUsing1 16:19:01,125 INFO [EntityBinder] Bind entity com.transparentpolitics.core.persistence.IdUsing1 on table IdUsing1 16:19:01,125 DEBUG [AnnotationBinder] Processing com.transparentpolitics.core.persistence.IdUsing1 property annotation 16:19:01,125 DEBUG [AnnotationBinder] Processing com.transparentpolitics.core.persistence.IdUsing1 field annotation 16:19:01,125 DEBUG [AnnotationBinder] Processing annotations of com.transparentpolitics.core.persistence.IdUsing1.transid 16:19:01,125 DEBUG [Ejb3Column] Binding column transid unique false 16:19:01,125 DEBUG [AnnotationBinder] transid is an id 16:19:01,125 DEBUG [AnnotationBinder] Binding component with path: com.transparentpolitics.core.persistence.IdUsing1.transid 16:19:01,125 DEBUG [AnnotationBinder] Processing com.transparentpolitics.core.persistence.TransPolId field annotation 16:19:01,125 DEBUG [AnnotationBinder] Processing annotations of com.transparentpolitics.core.persistence.TransPolId.id 16:19:01,125 DEBUG [Ejb3Column] Binding column id unique false 16:19:01,125 DEBUG [AnnotationBinder] id is an id 16:19:01,125 DEBUG [SimpleValueBinder] building SimpleValue for id 16:19:01,125 DEBUG [PropertyBinder] Building property id 16:19:01,125 DEBUG [PropertyBinder] Cascading id with null 16:19:01,125 DEBUG [AnnotationBinder] Bind @Id on id org.hibernate.AnnotationException: com.transparentpolitics.core.persistence.TransPolId has no persistent id property at org.hibernate.cfg.AnnotationBinder.bindId(AnnotationBinder.java:1686) at org.hibernate.cfg.AnnotationBinder.processElementAnnotations(AnnotationBinder.java:1170) at org.hibernate.cfg.AnnotationBinder.bindClass(AnnotationBinder.java:699) at org.hibernate.cfg.AnnotationConfiguration.processArtifactsOfType(AnnotationConfiguration.java:353) at org.hibernate.cfg.AnnotationConfiguration.secondPassCompile(AnnotationConfiguration.java:265) at org.hibernate.cfg.Configuration.generateDropSchemaScript(Configuration.java:682) ... 20 more @Embeddable public class TransPolId implements Serializable { @Id @GeneratedValue public Long id; @Override public boolean equals(Object o) { if ( o instanceof TransPolId ) { return ((TransPolId)o).id.equals(id); } return false; } @Override public int hashCode() { return id.hashCode(); } } @Entity public class IdUsing1 { @EmbeddedId public TransPolId id; public String value; } -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
