For all those who were having problems with ZSyncer and bobobase_modification_time, I believe its because there isnt a bobobase_modification_time for broken products. So if you have any broken products, fix them (on both ends) and ZSyncer should work fine. I'll throw this patch into ZSyncer soon. Is there a sure fire if telling if an object is "broken"? In the meantime heres the patch: --- OldZSyncer.py Tue Jul 10 12:32:38 2001 +++ ZSyncer.py Tue Jul 10 12:30:17 2001 @@ -210,7 +210,8 @@ # go find the folder, then iterate through the subject for ob in self.restrictedTraverse(string.split(folders, '/')).objectValues(): # we dont to sync ZSyncers, that way leads much confusion - if ob.meta_type != 'ZSyncer': + if ob.meta_type != 'ZSyncer': + if ob.meta_type[:14] == 'Broken Because': continue o = {} o['id'] = ob.getId() o['path'] = ob.getPhysicalPath() Cheers. -- Andy McKay.
