Since Orbeon Forms 2017.2, you can enable the lease feature, on any or all your forms. If, in your setup, it is possible for multiple users to edit the same form data, you'll want to enable this feature to eliminate the possibility of conflicts, which is done by Orbeon Forms ensuring that at any given time at most one user can edit a given form data.
Until now, when users couldn't edit form data because another user owned the lease on that form data, they needed to wait for the lease to be released before they could edit the data. Since Orbeon Forms 2020.1, alternatively, they can ask Orbeon Forms to show the data in read-only mode.
We hope that you will find this enhancement to be useful.
