   Well, darn! That's what I thought I have.

   In the OpenDB() function I have

 	Publisher().sendMessage(self.appData.projOpen, data=None)

and in the class modPolicy()'s __init__() method I have

 	Publisher().subscribe(self.setWidgets, self.appData.projOpen)

with setWidgets() a function that places values in the treeCtrl.

   But the error is still that the subscribe method has no arguments:

   File "/data1/eikos/policyPage.py", line 124, in __init__
     Publisher().subscribe(self.setWidgets, self.appData.projOpen)
   File
"/usr/lib/python2.4/site-packages/wx-2.6-gtk2-unicode/wx/lib/pubsub.py",
line 638, in subscribe
     self.validate(listener)
   File
"/usr/lib/python2.4/site-packages/wx-2.6-gtk2-unicode/wx/lib/pubsub.py",
line 670, in validate
     raise TypeError, 'Listener '+istener+' lacking arguments!'
TypeError: Listener <bound method modPolicy.setWidgets of
<policyPage.modPolicy; proxy of C++ wxPanel instance at
_00534408_p_wxPanel>> lacking arguments!

   Should the Publisher().subscribe() be located somewhere other than in the
init method?
