migration ManyToMany

Hi Dears

I want to user some thing like contacts of account for my entity so I apply below migration:

PHP

public function up(Schema $schema, QueryBag $queries ) { self::centerTable($schema,$this->extendExtension); $center = $schema->getTable('websys_center'); $contact = $schema->getTable('orocrm_contact'); $targetTitleColumnNames = [ "name_prefix", "first_name", "middle_name", "last_name", "name_suffix" ]; $targetDetailedColumnName = [ "name_prefix", "first_name", "middle_name", "last_name", "name_suffix" ]; $targetGridColumnNames = [ "email" ]; ///table name oro_rel_475cee1283dfdfa4334015 //index of default_contact in center FK_37B40600A56CA738 $this->extendExtension->addManyToManyRelation($schema, $center, 'contacts', $contact, $targetTitleColumnNames, $targetDetailedColumnName, $targetGridColumnNames, [ 'extend' => [ 'without_default' => false, 'is_extend' => true, 'owner' => ExtendScope::OWNER_CUSTOM ] ] ); }

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36

public function up(Schema $schema, QueryBag $queries )     {             self::centerTable($schema,$this->extendExtension);           $center = $schema->getTable('websys_center');           $contact = $schema->getTable('orocrm_contact');           $targetTitleColumnNames = [             "name_prefix", "first_name", "middle_name", "last_name", "name_suffix"         ];         $targetDetailedColumnName = [             "name_prefix", "first_name", "middle_name", "last_name", "name_suffix"         ];         $targetGridColumnNames = [             "email"         ];           ///table name oro_rel_475cee1283dfdfa4334015           //index of default_contact in center FK_37B40600A56CA738         $this->extendExtension->addManyToManyRelation($schema,             $center, 'contacts',             $contact, $targetTitleColumnNames, $targetDetailedColumnName, $targetGridColumnNames,             [                 'extend' =>                     [                         'without_default' => false,                         'is_extend' => true,                         'owner' => ExtendScope::OWNER_CUSTOM                     ]             ]         ); }

but when I want to save a new instance of my entity I have this error:

Fatal error: Call to a member function add() on a non-object in ../public_html/vendor/oro/platform/src/Oro/Bundle/FormBundle/Form/EventListener/MultipleEntitySubscriber.php on line 82

my entity :

could you help me?

I debug code and I see that FormBuilder can not build contacts of center form correctly.
