[GoogleCodeExporter]

What steps will reproduce the problem?

What is the expected output? What do you see instead?
the annimation to stop

What version of the product are you using? On what operating system?
pymt 0.4b1, windows xp

Please provide any additional information below.

Tito told me to stop an animation using the widget returned in a
widget.do(anim).     wid = widget.do(anim)

It works great, except when the animation is complex, like anim = anim1 +
anim2 + anim3 + ...

The error returned is : 
  File "C:\eclipse\workspace\touchpy\teste\Main.py", line 23, in touch
    self.widget_returned.stop()
AttributeError: 'NoneType' object has no attribute 'stop'
Exception AttributeError: "'NoneType' object has no attribute 'print_exc'"
in <bound method LoaderPygame.__del__ of <pymt.loader.LoaderPygame object
at 0x024BCD30>> ignored

HERE IS AN SIMPLE EXAMPLE

from pymt import *

class Anyclass():
    def __init__(self):
        self.window = MTWindow()
        self.window.push_handlers(on_touch_down=self.touch)

        self.widget = MTScatterWidget()
        self.window.add_widget(self.widget)

        self.animobj1 = Animation(duration=10, pos=[100,100], type = "delta")
        self.animobj2 = Animation(duration=10, scale=1.1, type = "delta")
        self.animobj = self.animobj1 + self.animobj2 

        self.animated = False
        self.widget_returned = None

    def touch(self,touch):
        if self.animated == False:
            self.animated = True
            self.widget_returned = self.widget.do(self.animobj)
        else:
            self.widget_returned.stop()
            self.animou = False

anyclass = Anyclass()

Fixed, the sequence and parallel animations needs more structuring it seems
