setting container class to hidden hides the element in editor

joomla 3.8.12
cc6 6.0.7
​
If I set the container class of a textarea to hidden the item disappears from the editor after pressing Apply or saving the connection.

REPLICATED
​
Just for additional information - he means the textarea element INSIDE a Fields element. Not a standalone field.

The problem is there for dropdowns too.
I didn't try but I suppose that every field with a container class setting is going to disappear when adding the hidden value.
​
I my opinion this should be fixed ASAP.

Thank you

Probably not going to be fixed, since the Fields element is deprecated and no longer used.

Do you know what is going to happen to a CCV6 connection that uses the Fields object when updating?
There's no Fields Element in CC 6.0.10.

Nothing. It's still there, just hidden.

As a workaround:

1. in phpmyadmin edit the record of the connection in #__chronoengine_connections6
2. in the view field value search for hidden or for the name of the item
3. in the group of parameters of that item search for container_class and then for hidden
4. change hidden to hiddex (or remove hidden)
5. save the record
6. edit the connection in chronoconnectivity

Or just go to libraries/cegcore2/administrator/extensions/chronofc/views/whatever's it's called and there's a line in the .ini file you can change to show it again.
