I am playing with a few ways to solve a problem and one involves using repeating single line and number fields. For the number fields (which will hold a 16-digit number) I added a default value of "0000000000000000" but when you click the little plus to add another line it doesn't have the default value.
Hello, I see the issue you have described and I'm able to replicate it in a local test site. I am escalating this to my 2nd tier support team for additional investigation, because the behavior here seems different from the behavior in wp-admin. In the admin side, the default value is applied to new field instances as expected. I'll let you know what I find out after escalating the problem.
Christian is currently on vacation, however I checked on the escalated thread for you. It would appear that the issue has been escalated to our development team.
I'm not seeing where the developers have made a comment on the issue as yet. Currently the latest is that the team is aware of the issue at hand.
There is no indication at the moment, so I would guess in the months range as opposed to the days or weeks range. Development cycles typically last around a month, so if an issue is not slated for the current development cycle it will probably not be addressed within 4 weeks. Since the issue has not yet been slated for the current development cycle, I would suspect at least that long unless the developers pick it up and add it to the current cycle. If that happens, I will update the ticket here and let you know.
