Same problem in 7.6.16, required input fields are not saved on the initial save. The data is not transferred in the POST. Downgrade to 7.6.15 fixed the problem

@Markus H.
Can you reproduce the issue reliably? Does your instance involve JS code from extensions?
Can you do a git bisect to find the offending commit?

The following changes have been merged between .15 and .16, which touch JS somehow:
https://review.typo3.org/51262
https://review.typo3.org/51816
https://review.typo3.org/51718

Don't know if those actually interfere here though.

@Markus K.

We reproduced the bug in different TYPO3 instances. Every time a new data is inserted. I tested with be_users, required fields are password, username and usergroup in a blank and new typo3 instance, and with own types of data in other instances.

Fields with default values and fields, which are not required, are updated properly.

We found some possible issues in reviews and will test them. I'll give you feedback.

i had the same problem here some time ago, so i think it's not related to 7.6.16
the first time i see this issue i used current Chromium version as Browser, so i thought it's related to some new stuff in Chromium.
Maybe a JS Event is not fired every time or something like that. Because the Problem is, that the input of the fields are not transfered to the hidden input fields, which are sent.

My colleague had reproduced it with TYPO3 7.6.13 AND Chrome Version 57.0.2987.98 (64-bit) Mac. We can't reproduce the problem at the same time with Firefox for example.

So I could anybody of you can reproduce it with e.g. Firefox or IE?

Encountered the same issue here in 7.6.16 (Chrome 57.0.2987.110 (64-bit)).

Same here.

Typo3 Versions 7.6.15 and 7.6.16, Chrome 57.

I can not reproduce the bug in Firefox.

This happens for all fields and not just in required fields! Tested with Typo3 Header CE and various Fields in Extensions.
Tested with all custom Extensions turned off in Chrome.

Please apply the patch of #80459: https://review.typo3.org/52168 and check if things got better.
Feedback very appreciated.

hi,

testet it with 7.6.16.
the Problem still exisit.

the problem is here locatated (TYPO3 7.6.16)

Any idea on when 7.6.17 will be available with this fix?

I guess I've stumbled upon this issue on a fresh 8.7.0 install (I am not able to reproduce at the moment, just guessing)
