In attempting to avoid rewriting the
Mage_Checkout_Block_Onepage_Shipping_Method_Additional block, I've been following my current strategy of removing the block with the old class and adding a new one with my new class:
<checkout_onepage_shippingmethod> <remove name="root" /> <block type="my_checkout/onepage_shipping_method_additional" name="my.root" as="root" output="toHtml" template="checkout/onepage/shipping_method/available.phtml" /> </checkout_onepage_shippingmethod>
This works great for non-root blocks, but my alias technique doesn't seem to work in this case. Any ideas?
PS: I'm aware that this can be done with a rewrite.
