NULL on IntegerConverter
f.e. i have a model wich holds a property "maxOrders".
NULL represents "unlimited"
0 represents 0
1 represents 1
so i have an input field where the user should be able to empty it with the
result that db field contains NULL (unlimited)
so in my humble oppinion the integer converter should convert nothing to null.
maybe in combination with a check of @ORM\Column(nullable=true)?
maybe the combination with @ORM\Column(nullable=true) could be also in any other converter?
