TYPO3 Core

If we disable a field with TCEFORM we don't want it to render but he should be able to edit it. If we must put a default value for a user without letting him see the field in the form we can't use the disabled option anymore.

example :
In the form of a content properties we disable the colpos field. On page module if we want to create a content in the left column the content is created in the center column because the user is not allowed to edit the colpos field.
