[Zope] TransientObjectContainer.keys()

[Edward Muller]

Agreed. doesn't this work:


keys = TransientObjectContainerInstance.keys()
for key in keys:
	print key

The above should print the TransientObjects in the
TransientObjectContainerInstance....

Again ... I've never read the code ... but that's the way session
works...
