In your extension you should have this file:

[Namespace]/[Module]/Block/Adminhtml/[Entity]/Edit/Form.php or something similar. This is the form container class.

Inside that file you should have a method _prepareForm that should look like this:

protected function _prepareForm()
{
    $form = new Varien_Data_Form(array('id' => 'edit_form', 'action' => $this->getData('action'), 'method' => 'post'));
    $form->setUseContainer(true);
    $this->setForm($form);
    return parent::_prepareForm();
}

Make sure that the id you pass to the Varien_Data_Form constructor is edit_form.
Use the cms page module as an example: (Mage_Adminhtml_Block_Cms_Page_Edit_Form).

$this->setChild('form_after', $this->getLayout()
    ->createBlock('adminhtml/widget_form_element_dependence')
        ->addFieldMap($accountField->getHtmlId(), $accountField->getName())
        ->addFieldMap($flatField->getHtmlId(), $flatField->getName())
