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=comments, but was rejected since no testcase was provided.
