Ability to get an element with creation options from the FormElementManager

[noopable]

Now we can get an element from the FormElementManager with only name.

$element = $FormElementManager->get('element', 'foo');
echo $element->getName();// foo

It is inconvenient not to have the 2nd parameter, 'options'.

would be also great to have the options parameter when we use
$form->add([
'type' => 'Element\Class'
'options' => $someOptions
]);

it seems also to be instantiated by the formelementmanager without the options parameter....

[noopable]

Yes, it is available.
But I said about FormElementManager's capability.
Sometimes, the FormElementManager is a gateway to get a customized form with creationOptions. And this is AbstractPluginManager's normal behavior.

$form = $formManager->get('Application/Form/Contact', $someOptions);

And so, the first parameter of FormElementManager::get is the name representing an instance. If we want to use class type, set it to Invokable or set the serviceConfig or set the di alias .
Invokable enables us to create an instance in simple use.
And new FormAbstractServiceFactory enables us to create a form with the serviceConfig.
And the di enables us to compose the form elements by di configuration.

But now the FormElementManager drops options for invokale.This PR will fix it.

@noopable That's why we have the Zend\Form\Factory.

@danizord
Thanks.
Can you tell me why AbstractPluginManager::get accept the 2nd parameter as CreationOptions?
Why does the FormPluginManager drop creationOptions though we cannot set even a label through it?
Is it just because there is factory?

It doesn't, though. If you write a custom factory, you will get the options; they will also be passed to invokables. That said, I think your approach makes a lot of sense, considering that the constructor for all objects under Zend\Form use $name as the first argument.

Merged to develop for release with 2.3, as it's a minor behavior change.
