For anyone looking for the answer to this question, I think I have stumbled
across the answer in the documentation. I needed to set the
'PrepareElements' decorator before handing over to the viewScript. This
ensures my subform elements now have the array notation I was expecting. As
an example, I have setup the following decorators:
$this->setDecorators(
array(
'PrepareElements',
array('viewScript', array('viewScript' =>
'decorators/myviewscript.phtml'))
)
);
And in my view script I can call:
echo $this->element->elementName;
This is mentioned in the documentation here
http://http://framework.zend.com/manual/en/zend.form.standardDecorators.html
Zend Framework Decorators (see Zend_Form_Decorator_PrepareElements)
