In Alfresco 6.1 enterprise and 6.2 community edition, trailing dot in folder name gives error.
Step to replicate: Try to create any folder with a trailing dot (.). Manually or using REST call. I raised it on Alfresco hub too.
Has anyone encountered this issue? Or anyone knows about any open defect on the same?
Are you talking about the "cm:name" property? If so, this is per specification.
