Add extra js in backend block (tab edit form) in Magento

I'm trying to add an extra js file to an admin block and I would like to do that by php code.

Scenario
My block is a tab block for admin edit form so it extends Mage_Adminhtml_Block_Widget_Form and implements Mage_Adminhtml_Block_Widget_Tab_Interface

My approach
In the tab block class __prepareLayout() method I have added this line:

 $this->getLayout()->getBlock('head')->addJs('folder/gallery.js');

This should be ok but actually is not importing any js.

Why not do this using layout XML? Ideally you would specify an adminhtml layout update file for your module, but you can add a local.xml file to the adminhtml/default/default/layout folder and in there do the normal <reference name="head"><action method="addJs">...</reference> call.

As suggested by @benmarks this is a particular situation but similar to the one described How to add JS programmatically in Magento?

The problem is the same 'head' block is already rendered.

I found a solution for this particular case ( add js in a edit tab form block in backend ):

to solve this I have added the above line in the _prepareLayout() method of the block that extends Mage_Adminhtml_Block_Widget_Form
