[html-formfu] $_->render_data->{value} returns only the first value for a many_to_many relationship

[Moritz Onken]

Hi,

I'm using $_->render_data->{value} to get a value of a field which got  
the data via $form->defaults_from_model.
If I try $_->render_data->{value} on a many_to_many relationship I  
only get the first value but not all of them. The element type is  
Select with multiple set to 1.
How can I get all (deflated) values?
