add property option

for example:

public function buildform(formbuilderinterface $builder, array $options) {     $builder->add('entityfields', 'entity' , array(         'class' => 'organisation\\mybundle\\entity\\myentity',         'expanded' => true,         'multiple' => true,         'required' => true,         'label' => 'mylabel',                    'query_builder' => function (repository $repository) {             return $repository->createquerybuilder('e')                     ->where('e.isactive = true');         },         'property' => 'customname'     )); } 

and in entity:

public function getcustomname() {     return $this->name.' '.$this->othercolumn; // etc }
