Hi Gregory, This is an issue with instances that descend from "ExtensionClass" (which your first class does). Read about the inheritedAttribute method in your Zope's lib/Components/ExtensionClass/doc/ExtensionClass.stx directory. - C Warnes, Gregory R wrote:
I've just modified a python product and I've started getting an error that doesn't make sense to me.
Here's the error message:
Error Type: TypeError Error Value: unbound method connect() must be called with instance as first argument [...] File /Volumes/app/appman/lib/zope/Zope-2.5.1-solaris-2.6-sparc/Products/RSessionD A/RSessionDA.py, line 213, in putFile (Object: RSession) File /Volumes/app/appman/lib/zope/Zope-2.5.1-solaris-2.6-sparc/Products/RSessionD A/RSOAP/localRSOAPConnection.py, line 124, in uploadFile (Object: RSession) File /Volumes/app/appman/lib/zope/Zope-2.5.1-solaris-2.6-sparc/Products/RSessionD A/RSOAP/localRSOAPConnection.py, line 49, in connect (Object: RSession) TypeError: (see above)
and the 'offending' code:
class RSession(localRSOAPConnection, SimpleItem): '''Connection object to the R Kernel'''
# no connect method defined here ... # ....
class localRSOAPConnection(RSOAPConnection):
def connect(self): flag = RSOAPConnection.connect(self)
if flag: self.__checklocal()
return flag
....
The localRSOAPConnection code works just fine in standalone Python. In Zope the localRSOAPConnection is extended by RSession with methods that are Zope-aware.
My question is why is the call to 'connect' failing in Zope? I am passing a valid instance with the self argument...
Ideas appreciated...
-Greg
