[TYPO3-core] RFC: #14430: disable_controls = list makes fields 'write_once'

[Stefan Geith]

This is an SVN patch request.

Type: bugfix

Bugtracker references:
http://bugs.typo3.org/bug_view_page.php?bug_id=14430

Branches:
trunk


Problem:
If you set
     'disable_controls'=>'list'
you can _once_ upload an image (or file). But because of a missing 
Delete-Button you never are able to change this image (or file) later.


Solution:
1) 'disable_controls'=>'list'
    should only remove the list, not the delete-button.
2) 'disable_controls'=>'list,delete'
    should only remove the list AND the delete-button.


Note:
Hope, this makes it into 4.4, because 'disable_controls=list'
is simply unusable without a delete-button ...

Another solution would be, to have an option
for overwriting files, if maxitems=1.
I have a patch for that in http://bugs.typo3.org/view.php?id=14432
But that is a new feature, and I think it wont make it into 4.4.


Patch attached.
