Delete link beetwen Ticket and task

I've registered this as ticket #409 because it looks like a bug.
Could you check by reading ticket #1 that it is realy not linked to the activity ?

Hi, I could not reproduce :

My test case :
Create activity #1
Create ticket #1, no parent activity
Create ticket #2, parent activity = activity #1
Delete activity #1 : error, 1 ticket linked
Delete ticket #2 : OK
Delete activity #1 : OK

Really, as the controle is based only on the existence of a ticket with idActivity = "1", if no item exists, th con,trole can't block.

Can you check in database : existence of Ticket where idActivity = the id of the activity you try to delete (even if the ticket is closed, the deletion of the activity is refused : the activity can only be closed, not deleted)
If issue persist, can you send print screen of details to Cette adresse e-mail est protégée contre les robots spammeurs. Vous devez activer le JavaScript pour la visualiser. ?

Thx.

What was wrong ?
