Changing date on form via Alt+C doesn't stick

[quant]

somewhat related error still exists (3.2.6.1). Not AV, but could be considered even worse because you will realize that sth got wrong too late ...

steps to replicate:

- create any item with date attribute (say appointment)
- go to form and click on date
- alt+c and choose and insert whatever date
- now move away form that item (by clicking on a different item in data explorer tree)
- now going back, you will see that the date you inserted was not saved

I find it hard to believe, because I use insert by calendar quite often ...
