There seem to be a bug on SPL level: ArrayObject does not report as Iterator with PHP 5.2.4. It implements ArrayAccess, which indirectly implements Iterator via ArrayIteartor.

This causes a bug when providing an empty ArrayObject to the partialLoop view helper.


<pre class="highlight">
<?php echo $this->partialLoop('catalog/products.phtml', new ArrayObject()) ?>


<pre class="highlight">
<?php $object = new ArrayObject() ?>
<?php echo $this->partialLoop('catalog/products.phtml', $object->getIterator()) ?>

To fix this in ZF, we need to add an extra check in the partialLoop helper that checks for ArrayObject:

<pre class="highlight">
if (!is_array($model) && (!$model instanceof Iterator or !$model instanceof ArrayObject)) { }

Actually, discovered that ArrayAccess does not implement ArrayIterator, but vice versa... meaning that ArrayObject does not implement Iterator. The correct behavior would be to check for Traversable, which would catch both Iterators and ArrayObjects, and would work with foreach().
