[TYPO3-core] RFC #11087: TCEForm does not replace the existing element if adding a new element to a field with maxitems=1

[Benjamin Mack]

Hey,

commited to trunk and 4.2. Thanks for testing.

I found another bug entry (#0006372: Insertion of more than one items by 
the Element Browser is allowed when it shouldn't) that I resolved as 
well, although my solution fixes only the selects with the size=1.
http://bugs.typo3.org/view.php?id=6372

My reasoning:
The problem is now solved for fields with size=1. For selects with a 
bigger size, there is an option to scroll, position and see multiple 
items, thus the behaviour is different and good in that way. So we have 
this now:

* If the size of the select is 1, then there is no sorting option, there 
is not even a way to see that there are multiple items. Thus, if there 
is only one item allowed, then there should always be one item in there.

* If the size of the select is more than one, then you can scroll 
through the items if there are more items than the size of the select. 
If there is a maxitems restriction, then there will be a exclamation 
mark item if you have too many items in there. You can scroll through 
the list and remove the appropriate item.


If anybody thinks that should be fixed for select size > 1, either 
repopen 6372 or open up a new bugentry.

All the best,
Benni.
