I have an external method that is trying to create a Transient Object Container in a 'temp_folder', as follows:

def BuildGarbageCollector(self):

folder = self.restrictedTraverse('Coz/TempImages') # Coz/TempImages already exists

folder.constructTransientObjectContainer(self, id='GarbageCollector', timeout_mins=10, limit=0,
delNotification=BASEFOLDER+'DeleteTempImage')

and I get the following error:

Traceback (innermost last):

AttributeError: constructTransientObjectContainer

If I change the external method as follows (remove the reference to 'folder'):

constructTransientObjectContainer(self, id='GarbageCollector', timeout_mins=10, limit=0,
delNotification=BASEFOLDER+'DeleteTempImage')

There is no error, but the TOC is created in the wrong folder. I can manually (thru the ZMI) add a TOC to the TempImages folder, but I can't create one programmatically.

Can anyone point me in the right direction?!
