Description

While fixing getErrors i had a closer look at ZF-5222 again,
as Vivek Chandran states there, mixing !isArray() SubForm with
SubForms and interferencing Name and elementsBelongTo segments,
data will be stripped because of array_merge or not merging at all.

$sub1->setElementsBelongTo('foo[bar]');
$sub2->setIsArray(false);
$form->addSubForm($sub1, 'bar')
     ->addSubForm($sub2, 'foo');
...
$values = array_merge($values, $this->_attachToArray($sub1->getValidValues(...), 'foo[bar]'));
// $values === array('foo' => array('bar' => ... ))
...
// next cycle
if (!$sub2->isArray()) {
    $values['foo'] = $sub2->getValidValues(...);
    // o.O
}
$sub1->setIsArray(false);
$sub2->setElementsBelongTo('foo[bar]');
$form->addSubForm($sub1, 'foo')
     ->addSubForm($sub2, 'bar');
...
if (!$sub1->isArray()) {
    $values['foo'] = $sub1->getValidValues(...);
    // $values === array('foo' => array('elem' => 'thisShouldBeKept'))
}
// next cycle
$values = array_merge($values, $this->_attachToArray($sub2->getValidValues(...), 'foo[bar]'));
// $values === array('foo' => array( 'elem' => 'thrownAway' ))
...

To check against similar failures in this parents previous SubTasks
i updated their tests to use the new Setup as well, however getValidValues
is the only one to fail from the commited patches.

before Patch

...
        foreach ($this->getSubForms() as $key => $form) {
            if (isset($data[$key]) && !$form->isArray()) {
                $tmp = $form->getValidValues($data[$key]);
                if (!empty($tmp)) {
                    $values[$key] = $tmp;
                }
            } else {
                $tmp = $form->getValidValues($data, true);
                if (!empty($tmp)) {
                    $fValues = $this->_attachToArray($tmp, $form->getElementsBelongTo());
                    $values = array_merge($values, $fValues);
                }
            }
        }
...

after Patch

...
        foreach ($this->getSubForms() as $key => $form) {
            $merge = array();
            if (isset($data[$key]) && !$form->isArray()) {
                $tmp = $form->getValidValues($data[$key]);
                if (!empty($tmp)) {
                    $merge[$key] = $tmp;
                }
            } else {
                $tmp = $form->getValidValues($data, true);
                if (!empty($tmp)) {
                    $merge = $this->_attachToArray($tmp, $form->getElementsBelongTo());
                }
            }
            $values = array_merge_recursive($values, $merge);
        }

This patch fixes the issue and updates the Unit Tests of previous SubTasks
within this group as well, to make sure they do not suffer from similar
issues.
