ACL setting in backend not responding

[grillkoning]

Steps to reproduce the issue

made a fresh new extension (on a fresh Joomla install version 3.6.2), either following the documentation:
https://docs.joomla.org/J3.x:Developing_an_MVC_Component/Adding_ACL
or using JDeveloper to create an (otherwise empty) extension gives the same issue:

• set ACL on component level: OK
• set ACL on category level: OK
• set ACL on item level: inherits as expected but freezes on edit

result:

Did you try to refresh the browsercache (Ctrl + F5)
also can you check the chrome developer console to see what js error you have

[grillkoning]

Refreshing the browser (or using a different browser) makes no difference.
The console gives error
"permissions.js:1 Uncaught TypeError: Cannot read property 'value' of null"
the apache log gives no error

I see in your screenshot that it is not a core component. To remove the possibility that there is a bug in that component can you replicate this issue with any of the core components

[grillkoning]

no I couldn't ; tested with com_content which works just fine.

Sounds like an issue with that component then and not the core

[andrepereiradasilva]

that's probably because your component does not have a title field.

See #11296 (comment) for more info
i actually think the core should not force having a title field here...

anyway can you check that is the problem?

[grillkoning]

check; that indeed solves the problem. Thanks; i would have NEVER guessed that
