Pickerfield for references between entities from different data stores is not working well

I used the mechanism from here:
https://doc.cuba-platform.com/manual-6.10/manual.html#cross_datastore_ref

The datamanager is not loading the referenced entity again.

Maybe I need to write some postInit code for the editor?
Documenation: “DataManager can automatically maintain TO-ONE references between entities from different data stores, if they are properly defined.”

@NamePattern("%s|name")
@Table(name = "RICAREPORT_PRODUCT")
@Entity(name = "ricareport$Product")
public class Product extends StandardEntity {
    private static final long serialVersionUID = 6323743611817286101L;

    @Lookup(type = LookupType.SCREEN, actions = {"lookup"})
    @NotNull
    @Transient
    @MetaProperty(mandatory = true, related = "fndPortfolioViewId")
    protected FndPortfolioView fndPortfolioView;

    @SystemLevel
    @Column(name = "FND_PORTFOLIO_VIEW_ID")
    protected Long fndPortfolioViewId;

Unfortunately, we cannot reproduce the problem. Could you please provide more information about your problem? Which version of the platform do you use? We will be able to help you if you send us a small sample project along with reproduction scenario that demonstrates the issue.

The example was produced with 6.10.0. I know tried to rebuild the example with 6.10.1 from scratch for comparision reasons and now it works.
The only difference beside from minor version upgrade is that i selected the EdtiorCombined lookup.
Therefore the annotations changed. Maybe the @NotNull annotation was wrong for a transient field.

@NamePattern("%s|fndProtfolioView")
@Table(name = "RICAREPORT_PRODUCT")
@Entity(name = "ricareport$Product")
public class Product extends StandardEntity {
    private static final long serialVersionUID = 6722009556546732446L;

    @Transient
    @MetaProperty(related = "fndProtfolioViewId")
    protected FndPortfolioView fndProtfolioView;

    @SystemLevel
    @Column(name = "FND_PROTFOLIO_VIEW_ID")
    protected Long fndProtfolioViewId;

I think the issue can be close now.
Thanks
