Hi. I get smacked by this: [...long traceback...] * Module Products.CMFCore.CatalogTool, line 58, in allowedRolesAndUsers * Module Products.CMFCore.utils, line 200, in _mergedLocalRoles Exception Value can only concatenate tuple (not "list") to tuple The file tells me nothing special. I once fixed it by using merged[k] = tuple(merged[k]) + tuple(v) instead of merged[k] = merged[k] + v I don't know if i triggered something bad before, but this code seems to be somewhat ... instable ... so maybe forcing it into a tuple maybe a good thing.
