[TYPO3-dev] enforcement of uniqueness of fields

[Markus bertheau]

Hi,

in versions 3.8.1 and 4.0 when a field is unique typo3 enforces that
by appending a 0 so as to make the value unique (enter record one with
"a" in unique field, secord record with "a" in unique field too,
second record ends up with "a0"). This can cause quite some confusion.
In particular I have a customer who saves note records in typo3, that
have a note id field that looks like this:

N67
N102
N120

So when now someone accidentally enters N67 again, he will end up with
N670, which is a perfectly valid note id, but is just the wrong note
id for that note, and he is not notified of his mistake in any way. Is
there a way to make typo3 output an error in such cases and give the
user a chance to enter another note id?

Thanks
