TYPO3 Core

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

'disable_controls'=>'list,delete'
should only remove the list AND the delete-button.

Attached Patch does this.

This was fixed in f92873b30c59ca7bc7902617991175834589a11e and can be closed.

Sorry, but this was NOT fixed in f92873b30c59ca7bc7902617991175834589a11e

If you use
'disable_controls' => 'list'
then you will NEVER be able to delete this image again.

You may replace it with others, because now with maxitems=1 the image will be replaced,
BUT there is missing a way to DELETE the image, if you want to remove it completely.

Only alternative in the moment is to replace it by clear.gif :(

Ok, I see the point with the maxitems=1 case - we could hide the list for this case, and still show it (without the move controls) for maxitems > 1. Otherwise all (!) files are deleted when using the delete button if the list is not shown.

IF you set (manually) to NOT display the list,
then (at least for me) it seems clear, that with 'delete', the whole list is cleared.

Its up to the developpers to set the right values in TCA, so if you set this with maxitmes>1, you have to know, that delete will delete all files.

Yeah, right. Thought about that a bit longer now - and your approach is more logical than mine (I would have displayed the list for maxitems>1 if the delete button is shown - but that is a breaking change I guess).
