Answer 1

You could try to deactivate the validator:

in your Form.php

$field = $this->createElement('select', 'fieldname');
$field->setLabel('Second SELECT');
$field->setRegisterInArrayValidator(false);
$this->addElement($field);

The third line will deactivate the validator and it should work.

Answer 2

You may also add options to select element before checking for the form validation. This way you are insured the select value is in range.

Answer 3

Additionaly you should add you own InArray Validator in order to protect your db etc.

In Zend Framework 1 it looks like this:

$this->addElement('select', $name, array(
            'required' => true,
            'label' => 'Choose sth:',
            'filters' => array('StringTrim', 'StripTags'),
            'multiOptions' => $nestedArrayOptions,
            'validators' => array(
                array(
                    'InArray', true, array(
                        'haystack' => $flatArrayOptionsKeys,
                        'messages' => array(
                            Zend_Validate_InArray::NOT_IN_ARRAY => "Value not found"
                        )
                    )
                )
            )
        ));

Where $nestedArrayOptions is you multiOptions and $flatArrayOptionsKeys contains you all keys.

Answer 4

You can also disable the InArray validator using 'disable_inarray_validator' => true:

For example:

    $this->add( array(
        'name'     => 'progressStatus',
        'type'     => 'DoctrineModule\Form\Element\ObjectSelect',
        'options' => array(
            'disable_inarray_validator' => true,
        ),

    ));
