I wish this helpful for you I have a button inside an xpages div and I am trying to compute the style class of that button based on a scoped variable. , if you disable the theme for the button it should work
code :
<xp:button id="btn" disableTheme="true"></xp:button>

it fixes the issue Here's a fiddle with a directive to handle that: http://jsfiddle.net/g/LAJCa/
As mentionned in the comments, you should'nt do DOM manipulations outside directives, you'll not benefit a lot from angular if you don't respect the guidelines: http://docs.angularjs.org/guide/dev_guide.mvc.understanding_controller

help you fix your problem The only way you can really achieve what you're after is to use a unique classname (or ID) for each 'section' and then use inheritance to sort-of namespace your CSS. So if you want to target one specific section of the page, give it's parents a classname (eg: class="testone") and then make sure that any styles you want to apply to that section are appended with that classname:
code :
.testone .title{...}
.testone h1{...}
.testone a{...

wish of those help To solve this problem just add the line self.attr = self.attr inside the __init__ function of A. Since you don't want to change the attributes of A, you will have to make the following changes:
code :
class A(object):
    attr = None

    def __init__(self):
        assert self.attr is not None # Don't refer to A, but to self to get the correct value
        self.attr = self.attr


class B(object):
    def __init__(self, attr):
        self.attr = attr # Don't edit A, just save the value in own instance

    def __getattribute__(self, item): # completely added, does some magic to ensure class.attr is set correctly 
        if item in B.nested_classes:
            c = B.nested_classes[item]
            c.attr = self.attr
            return c
        return super().__getattribute__(item)

    class C(A):
        def __init__(self):
            super().__init__()

    class D(A):
        def __init__(self):
            super().__init__()

    nested_classes = {cls.__name__: cls for cls in {C, D}}


first_class = B("first")
first_sub_class = first_class.C()
print(first_sub_class.attr)
second_class = B("second")
second_sub_class = second_class.C()
print(second_sub_class.attr)
print(first_sub_class.attr)
Changing a variable within a class causes global variables to change as well?

it should still fix some issue In Python, there is no concept of "pass by reference" or "pass by value". Everything is "pass by name". That said, there is a difference between passing mutable and immutable objects.
You are passing the global weights, a mutable object, to the class constructor. Since it's mutable, it's sort of analogous to passing by reference. The scope in which you modify the object does not matter. Whether you use the name in the scope of the class (self.weights_new) or the name in the global scope (weights), the object is the same.
