Unclear error mesage

[roma2341]

I had @EntityView View1 with a lot of properties. Then i need to add View2 and reuse some properties from View1, so i moved them to BasicView interface so View1 and View2 extends this BasicView. But now queries that worked with View1 didn't work throwing exception that says nothing.

This BasicView extends another entity view:

@EntityView(MyEntity.class) @EntityViewInheritance() public interface CoreView

java.lang.NullPointerException: Cannot invoke "com.blazebit.persistence.SubqueryInitiator.from(String, String)" because the return value of "com.blazebit.persistence.SelectBuilder.selectSubquery(String, String)" is null

Tries both: <artifactId>blaze-persistence-bom</artifactId> 1.6.11

And 1.6.17

I think i made some error in mapping when moving out properties to common interface, but i think that error could be more helpful.

In my case issue happened because i extended my class in child EntityView instead of parent EntityView.
