Excerpts from Tim McMahon's message of 2018-01-02 16:26:39 -0600:
I'm testing 17.11 (package upgrade from 17.05.02) and when I try to enter a new patron, the Password and Confirm password fields in the OPAC/Staff login section near the bottom of the form will get labeled "This field is required."
I can confirm this behavior on my test VM of 17.11 Curiously, during my test of adding a new patron, the "required" labels on the Password and Confirm fields didn't appear when I first loaded the form. They only showed up after I hit the "Save" button, which failed to save, and presented me with the form again, this time with the labels added. I got around the problem by putting the word "junk" in for the passwords, and leaving the username blank. Then when I edited that patron again, I found that Koha had auto-generated a user name consisting of the first and last names of the patron concatenated with a "." separator. In summary, I couldn't find a way to enter blank usernames or passwords for patrons. I don't recall that 17.05 exhibited this behavior.
I also noticed that the primary and secondary email fields aren't validating either.
I didn't see a problem with these fields.
