I´m developing an application using Zend Framework 2 and I use FormRow helper to render a label, the input and errors (if present) in a Form.

See the code of formElementErrors

Basically you could do something like:
```
$this->formElementErrors($elem)
     ->setMessageOpenFormat('')
     ->setMessageSeparatorString('');
```
But that is quite unhandy...

The better solution would be to extend the Zend\Form\View\Helper\FormElementErrors by your own class and then register the view-helper formElementErrors to your class. So basically you'd have something like this:
```
namespace Mymodule\Form\View\Helper;

use Zend\Form\View\Helper\FormElementErrors as OriginalFormElementErrors;

class FormElementErrors extends OriginalFormElementErrors  
{
    protected $messageCloseString     = '
```

';
    protected $messageOpenFormat      = '';
    protected $messageSeparatorString = '

';
}

Last thing then would be to register the view helper with this new Class. For this you provide the following code inside your Modules Module.php

public function getViewHelperConfig()
{
    return array(
        'invokables' => array(
            'formelementerrors' => 'Mymodule\Form\View\Helper\FormElementErrors'
        ),
    );
}

displaimer: This code isn't tested, let me know if there are some errors, but i think this should work out quite well.
