[fw-general] Render Zend_Form from ajax action render() missing markup?

[Jonathan]

I have an econtracting system.  There are about 100 forms.  A person can 
select a form, and have it render right after they select it.  I am using 
ajax to call and get the correct form based on their selection, then passing 
back the rendered HTML to put in the form container (DIV).

The problem:  For some reason, when I render via the ajax action, it is 
missing the required field markup....the <span>&nbsp;*</span> markup that 
accompanies the "required" elements.

I tested it straight out by using the render() method from a non-ajax 
action, and it is also missing the markup.

Here is a segment of the code from the ajax action....(tried without the new 
Zend_View, as well as with $this->view).

$form = $this->_econSvc->getEcontractForm($params['formId']);

$response['econtractForm'] = $form->render(new Zend_View());


echo Zend_Json::encode($response);



Thank you so much for any assistance.
