Symfony2 forms interpret blank strings as nulls

Question

I have a Symfony2 form with a variety of fields, including one optional text field called recap.

This recap field saves perfectly when there\'s

Answer 1

Just came across similar error in Symfony2:

My entity:

/**
 * @ORM\Column(type="boolean")
 */
protected $Valid;

My form:

$builder->add('Valid', 'hidden');

Now for true values, field is rendered correctly with value="1", but for false values field is rendered with value="", which leads to:

SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'Valid' cannot be null

While I would expect it to be rendered as value="0".

Of course setValid() method can be enhanced to set the right value:

public function setValid($valid)
{
    $this->Valid = ($valid ? true : false);
}

Which work arounds the issue, not fixes it.
