Cannot get value from doctrine_orm_time filter with mapped set to false

[webdevilopers]

I have a doctrine_orm_time filter night_shift_start that is not mapped to my TimekeepingEntry admin:

$datagridMapper
            ->add('night_shift_start', 'doctrine_orm_time', array(
                'show_filter' => true,
                'field_options' => array(
                    'hours' => array(20, 22),
                    'with_minutes' => false,
                    'mapped' => false
                )
            ))

After setting the filter to a value and submitting I'm getting the following dump on the filter data in my custom CRUDController:

$datagrid = $this->admin->getDatagrid();
$datagridFilters = $datagrid->getFilters();
dump($datagridFilters);

As you can see the value index is not set and since then not available with:

echo $datagridFilters['night_shift_start']->getValue()['value'];

This seems to be caused by the mapped option. Setting the option to true and dumping without(!) submitting will show the expected format:

Submitting the filter is not possible:
TimekeepingEntry has no field or association named night_shift_start

Any idea how to solve this?

BTW: why does the mapped option have to be set on the field_options and not the general third parameter array?

I tried the following solution as workaround:

$nightShiftStart = $datagrid->getForm()->get('night_shift_start')->getData();

Seen on: http://stackoverflow.com/questions/20440836/sonata-admin-how-to-read-not-mapped-field

But the value will again be empty.

The only quick workaround I found:

$nightShiftStart = $request->get('filter')['night_shift_start']['value']['hour'];

This issue is very old. Can you please check this against the latest stable / master version?

Feel free to reopen, if the error still exists.

A PR would be welcome if you reopen this issue.
