Yep. You're using the ViewScript decorator to render your elements, so
you need to do a couple of things manually.
First, for each element, you need to do the following:
// simplified -- you should refactor to cache the form name
$element->setBelongsTo($form->getElementsBelongTo());
This is done implicitly in the FormElements decorator -- but since
you're using ViewScript on your form, you have to do it manually. I
would do this at the start of my view script before rendering anything,
using something like this:
$belongsTo = $this->element->getElementsBelongTo();
foreach ($this->element->getElements() as $element) {
$element->setBelongsTo($belongsTo);
}
Second, when rendering your elements, if you don't use the ViewHelper
decorator, you'll need to fetch the name and/or ID manually:
$element->getFullyQualifiedName(); // gets the fully qualified name
$element->getId(); // will use the FQN to create the id
