This makes no sense at all. > allAttributes > Description: Checks to see if any of the given attributes, match the given > condition. > Hopefully you actually mean "all", not "any". > What's funny here is that THESE TWO functions were the ones I initially > needed, and your documentation has errors for BOTH of them. I'll expect then > to find more errors in your documentation, and will report them to you as I > find them. > Feedback confirming the errors will be appreciated. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
