Hi, I am trying to migrate my cuba platform v6 project to the latest v7.2.
All my screens and datasources are still legacy v6 type.
I get the following NullPointerException when trying to open open an Entity editor from my DataGrid’s edit action. Would be grateful for any hints why this is not working!
javax.persistence.PersistenceException: java.lang.NullPointerException
at org.eclipse.persistence.internal.jpa.QueryImpl.getSingleResult(QueryImpl.java:560)
