Reproducing the bug

Description

Queries do not find the proper field on db when the field is renamed using @NameInDb

Code

@Entity
public class MyClass {

    @Id
    long id;

    @NameInDb("someField")
    String mSomeField;
}

List<MyClass> result = mBox.query()
                .equal(MyClass_.mSomeField, "some value")
                .build()
                .find();

Will look into this for the upcoming version. Thanks for reporting.

We could reproduce this using internal integration tests. -ut

I have same problem in a integration tests too

ObjectBox 1.4.1

[kirich1409]

But I have no @NameInDb on property

[greenrobot-team]

@kirich1409 ObjectBox can not handle float arrays out of the box (I assume Sample.property is one because the error messages indicates the type descriptor is L[F;). Have you specified a custom type converter? -ut

[kirich1409]

Yes. I've specified custom type converter annotation

[kirich1409]

I think it maybe Kotlin setting annotation on property, need to try it in Java code

@kirich1409 @rogerou Could you post the property definition in your entity including its annotations?
