[Flow] Optional DateTimeConverter

[Zedd]

Hi,

with "@ORM\Column(nullable=true)” you merely tell Doctrine to make that column nullable.
To actually make the property optional, you need to have a function signature like this:

public function setStopDate(\DateTime $stopDate = NULL) {}

Also, setting stopdate to NULL in the constructor does nothing but confuse anyone looking at it.

Greetings
