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

[Paolo "Nusco" Perrotta (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/ANN-539?page=comments#action_25876 ] 

Paolo "Nusco" Perrotta commented on ANN-539:
--------------------------------------------

Sorry, I thought embedded HTML worked in JIRA. Again:

This is almost certainly the same bug that causes ANN-526 (http://opensource.atlassian.com/projects/hibernate/browse/ANN-526). I hope to have it fixed soon.

> 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.
