I had defined the attibute as an array()....

        $corporate_wallets = new Select('wallets_subscribed[]', $wallets, array(
            'multiple' => 'multiple',
            'useEmpty' => TRUE,
            'emptyText' => 'Select Wallets',
            'emptyValue' => '',
        ));
        $corporate_wallets->addValidators(array(
            new MultiSelectValidator(array(
                'message' => 'Choose atleast one  Wallet Types',
                    ))
        ));
        $corporate_wallets->setAttribute('id', 'wallettypes');
        $corporate_wallets->setLabel('Select Wallet Types');
        $this->add($corporate_wallets);

Hi @jaikumar002 Can you try with this please and tell me, use a generic name and set the real name in attribs

$corporate_wallets = new Select('walletsElement', $wallets, array(
            'multiple' => 'multiple',
            'useEmpty' => TRUE,
            'emptyText' => 'Select Wallets',
            'emptyValue' => '',
            'name' => 'wallets_subscribed[]'
        ));

How do you validate the form? $form->isValid($this->request->getPost())???
