php - Extraneous option field in Symfony2 form -


i'm using symfony version 2.5.4 , have builder looks this.

$builder->add('licensed', 'choice', array(     'choices' => array(         'n/a' => '--',         'yes' => 'yes',         'no' => 'no'     ),     'required' => false,     'label' => 'somelabel',     'label_attr' => array('class' => 'font-bold'),     'attr' => array('class' => 'rounded')     ) );

when render form get:

<select id="companyotherinformation_licensed" name="companyotherinformation[licensed]" class="rounded">         <option value=""></option> <-- not sure coming from.         <option value="n/a">--</option>         <option value="yes">yes</option>         <option value="no">no</option> </select>

there's <option value=""></option> have no idea how got there. can find out came , rid of it? symfony2 bug?

i've tried app/console cache:clear , i'm still not able rid of it.

not bug:

http://symfony.com/doc/current/reference/forms/types/choice.html#empty-value

if leave empty_value option unset,  blank (with no text) option automatically added if ,  if required option false:

so add: 'empty_value' => false

but think it, setting required = false implies that user not have select anything. options, have no choice. having required = true make more sense.
