I am new to Zope; working through the Zope Book. I created a version object to test out this functioality, made changes to some objects etc. However, perhaps I didn't have 'cookies' configured properly, but some versioned changes were published on the save command and others were not. I tried to backout of what I had done using the 'Undo' feature, but it seems that I have created a right old mess now! The problem is that there is a version lock on a folder that I can't get rid of. If I start the version and then try to view the contents of the folder concerned I get this error message : Changed in a Version Site Error An error was encountered while publishing this resource. Error Type: POSKeyError Error Value: 000000000000332b Is there any way of forcing a delete version / remove lock so that I can at least try again, as opposed to uninstalling / reinstalling the whole Zope server and database?
