No problem, I'm glad my suggestions worked for you.
By 'echoing the whole form', I mean you were doing a <?= $this->form ?> in
the view. I thought you were using ViewScript on the elements only and not
the form. renderForm() is only useful if you're doing something like
// controller
$this->view->form = new Form_Foo();
// view
<?= $this->form->renderForm(false) ?>
<?= $this->form->foo ?><br />
<?= $this->form->bar ?><br />
<?= $this->form->submit ?>
</form>
A decorator does not necessarily wrap the output of the preceding
decorator(s) though. It may append, prepend, wrap, or even completely ignore
and replace the previous output with something else. The default behavior of
most decorators is 'append', so what happened there was the output of the
ViewScript was appended to the empty form which was returned by Form. (I
don't know what PrepareElements does, apparently it doesn't touch the string
passed to it). The 'placement' option allows you to override the default
behavior in some decorators.
