* Those private variables are just a step to make easier refactorisation of this file, to have a global overview about what is set in this helper, and to move easely piece of code to new methods:
* The methods get/set the private variables, and defore calling get_defined_vars, variables are created from those private variables.
* It's just a first step. get_defined_vars should be removed, and most of the private variables here should be moved to the correct object:
