Description

« Hide

if an entity class has a property of type embeddable, when trying to filter by a property of the embedded property, hibernate attempts to filter by a nonexistent property of the parent entity and throws an exception
example:

@Entity
public class Foo {
    private Bar bar;
    public Bar getBar() {return bar;}
    public void setBar(Bar bar) {this.bar = bar;}
}

@Embeddable
public class Bar {
    private String baz;
    public String getBaz() {return baz;}
    public void setBaz(String baz) {this.baz = baz;}
}

Foo filter = new Foo();
Bar bar = new Bar();
bar.setBaz("baz");
filter.setBar(bar);
FooDAO.findFiltered(filter);

yields the following:

org.hibernate.QueryException: could not resolve property: baz of: Foo

It appears to occur also for properties marked with @Transient and/or setter methods that do not correspond to an actual persisted field. Example:

@Entity
public class Foo {
  private Bar bar;
  public Bar getBar() {return bar;}
  public void setBar(Bar bar) {this.bar = bar;}
  public void setBar2(Bar bar2) {this.bar = bar2;}
}

Foo foo = new Foo();
foo.setBar(new Bar());
fooDAO.findFiltered(foo);

yields:

org.hibernate.QueryException: could not resolve property: baz2 of: Foo

Committed a proposed fix (still work in progress, need to implement some functionality like filterMetadata support) with revision 2623 (sorry, wrong issue number in commit message)
