Access Issues

[O'Rourke Clodagh-corour01]

Hi all,

I wonder if anyone can help.

I am trying call the constructor of the EnvVar class from the newEnvWin function of the Cell class.
But I am getting the following error

Exception in Tkinter callback
Traceback (innermost last):
  File "/usr/vob/omc_reference/ThirdParty/scriptSources/lib/python1.5/lib-tk/Tkinter.py", line 764, in __call__
    return apply(self.func, args)
  File "Cell.py", line 63, in newCellMgt
    self.newEnvWin('cellmgt')
  File "Cell.py", line 60, in newEnvWin
    instance = EnvVar.__init__(g, self.parent)
AttributeError: __init__

I have include some extracts of the code.
Thank you,
Clodagh.
