Re: [fw-mvc] Problems using "belongsTo" on an element within a "subform"

I think I may have found the answer, although again I could be wrong. I think
it needed some code in the main Zend/Form.php file within the isValid()
method. I will try to report my findings to ZF team through the Issue
Tracker, but basically I added a new piece of code to find nested arrays.
This is prefect for my site and will help me continue, but the actual code
would probably need more work.

Within the isValid() method I have replaced:

foreach ($this->getElements() as $key => $element) {
$element->setTranslator($translator);
if (!isset($data[$key])) {
$valid = $element->isValid(null, $data) && $valid;
} else {
$valid = $element->isValid($data[$key], $data) && $valid;
}
}

with:

foreach ($this->getElements() as $key => $element) {
$element->setTranslator($translator);

if (null != $element->getBelongsTo()) {
$parent_array = $data[$element->getBelongsTo()];
$key = $parent_array[$key];
$valid = $element->isValid($key, $data) && $valid;
} else {

if (!isset($data[$key])) {
$valid = $element->isValid(null, $data) && $valid;
} else {
$valid = $element->isValid($data[$key], $data) && $valid;
}
}
}
