wxPython ListCtrl_edit and TextEditMixin on mac OS X 10.4

[Sven Tissot]

Hello,

I am trying to build an editable ListCtrl_edit via TextEditMixin.
It displays o.k. and I can edit the first field with this is the code piece:

class VokabelListCtrl(wxListCtrl,
                    listmix.ListCtrlAutoWidthMixin,
                    listmix.TextEditMixin):

     def __init__(self, parent, ID, pos=wxDefaultPosition,
                  size=wxDefaultSize, style=0):
         wxListCtrl.__init__(self, parent, ID, pos, size, style)
         listmix.ListCtrlAutoWidthMixin.__init__(self)
         #listmix.TextEditMixin.__init__(self)


uncommenting the TextEditMixin still renders the ListCtrl, but as soon 
as I click into the grid the application crashes with a

IndexError: tuple index out of range

Traceback (innermost last):

__getitem__
   def __getitem__(self, index):        return self.Get()[index]


what is my mistake ??? Can anybody give me a hint ?

P.S. I installed the curent wxPython release and applied the following

     *  download and install 
http://pythonmac.org/packages/TigerPython23Compat.pkg.zip

     * used multiversion install via adding
           o import wxversion
           o wxversion.select("2.6")


kind regards,
Sven
