Hello,
It may happen that error message "Error: the object has already been created!" is displayed when a creation form is submitted. Here is a way to reproduce it:
in tab #2, openany mage of the application
go for lunch or give enough time to the session to time out
Session has timeout while creation form was open but browser has not been made aware of it...
Best regards,
Christophe
Since 2.2.0 the system is protected against session loss. This procedure to reproduce the bug is no longer effective. But this may happen in other circumstances ...
