Display required field error message on the Review and Decision forms
Description; on submit action blank fields with the validation option set to 'required' should display an error message for all form fields types. Including ThreadedDicussion
Feedback from @BenWh
We have the outstanding issue he mentioned, that in the decision and review forms the little validation warning messages don't appear on any field that hasn't yet been touched by the user (even though validation correctly prevents the form being submitted, and even scrolls you back up to the first field that needs fixing. This is really a bug with dynamic forms, unrelated to threaded discussions.
I suspect it may be fixed if we create initial values for the form more carefully, supplying a dummy null value for every field.
