Zend - Add subForm to existing display group

In my controller I got a function which looks like this:

public function newExperienceAction() {
        $this->_helper->layout->disableLayout();
        $ajaxContext = $this->_helper->getHelper('AjaxContext');
        $ajaxContext->addActionContext('newExperience', 'html')->initContext();

        $id = $this->_getParam('id', null);

        $this->form = new Application_Form_Cv();
        $this->experience = new Zend_Form_SubForm();
        $this->form->addSubForm($this->experience, 'experience');
        $rowExperience = new Application_Form_Experience();
        $rowExperience->setDisplayGroups('experience');
        $this->experience->addSubForm($rowExperience, "experience$id", $id+3);

        echo $rowExperience->__toString();
    }

When the user press (+) on the form, a new subForm will be displayed.

I'm currently in the process if shaping it into a table. I will have more than one subForm on this form so I need to use DisplayGroups.

In this situation, I believe I have to create a Display group when the form is first created.

Then I need to append the new subForms to the existing display groups.

So the question:

How do I add new subForms to an existing display group?

I'm afraid this is not possible now. I'm using Zend Framework version 1.11.7 and the code of the addDisplayGroup method looks like that:

foreach ($elements as $element) {
    if($element instanceof Zend_Form_Element) {
         (...)
    }

    if (isset($this->_elements[$element])) {
        (...)
    }
}

So this is not supported yet. You can add only Zend_Form_Element instances

You can achieve this by simply adding

$rowExperience->setIsArray(true);

This causes the sub-form to act like a display group, i.e. its values are wrapped in an array indexed by the sub-form's name (experience$id in your case).
