I lost data when modifying an entity that references another entity of another DataStore.

I have another DataStore: otherStore, connected via REST DataStore, in otherStore there is an entity “User”.

And I have an entity “Contract” in the Main Data Store, in “Contract” I have a field “user” that links to the table “User” in otherStore and @DependsOnProperties field: “userId”.

Contract List Screen:

I have a contract edit screen with fetchPlan="_base".
Contract Edit Screen(fetchPlan="_base"):

After I edit the “name” field and save, the “user” and “userId” fields data are lost:

Same when I run BPM process when I use: Entity Data Task. I also lost data feild “user” and “userId”:

Can you explain and give me any solution or suggestion?

Hi Krivopustov

Thanks for fixing the above bug in version 2.4.2.

But I have a new problem when creating ContractProvider table and @ManyToOne reference to Contract and when I open edit screen with full fetchPlan I get error like this:

Could you provide a test project or at least the detailed explanation of all entities and views, and the full stack trace?
