Many times I see
parent::preDispatch() or for example
parent::validate() withing actions / functions of magento.
I don't really understand the concern of that parent calls. Can you explain that please on Account Controller of magento.
Today I was working with Account Controller and need to add new action.
I was overriding preDispatch method, but that override doesn't work until I commented
I decided with the solution to replace
parent::preDispatch code with
Mage_Core_Controller_Front_Action::preDispatch() but not sure if that right or not.
p.s. One day I was overriding validate method of the payment method, that doesn't work also until I commented parent::validate.
