Primary keys must _never_ be updated. They are what EOF uses to uniquely identify the object.

Yeah, what he said :-)

I would add that unless you absolutely have to (are tied to a legacy model for instance) do not save "real" data in the pk. Make it a database artifact only, hide it as a class property and let EOF handle it for you. Move your real data to another attribute. Your application will thank you.

Hello;

I have a single page that encounters an error when I try to save changes. This is the only page in the application that has this problem. I have included the error from the console, are primary keys not allowed to be updated through the EO Model?

UsersWo, saving changes: cannot update primary-key 'registrati' from '200500' to '200501' on object:{values = {registrati = "200501"; rma = 0.0; tracking = 2.005E8; }; this = "<TechHelpSetup d3e679 _EOVectorKeyGlobalID[TechHelpSetup (java.lang.String)200500, (java.lang.Double)0.0,(java.lang.String) ,(java.lang.Double) 2.005E8]>"; } of entity: TechHelpSetup in databaseContext

Thanks,

Don
