Exception when two parameters named identically
-----------------------------------------------
Key: JRUBY-5571
URL: http://jira.codehaus.org/browse/JRUBY-5571
Project: JRuby
Issue Type: Bug
Affects Versions: JRuby 1.6RC3
Environment: JRuby running in 1.9.2 mode
Linux rupert-laptop 2.6.32-29-generic #58-Ubuntu SMP Fri Feb 11 19:00:09 UTC
2011 i686 GNU/Linux
Reporter: Robert Pankowecki
Assignee: Thomas E Enebo
def self.without_rejected_or_cancelled_requests(query, _, _)
query.with_statuses(:pending, :approving, :approved).not_cancelled
end
As you can see there are two parameters in this method that are not used in the
body and are named the same way as underscore. I had two different exceptions
when looking around this bug. Renaming the parameters to _a, _b solved the
issue.
Exceptions:
A) When running from rake test
1) Error:
test_approvals_are_created_on_pending(Absence::ApprovalTest):
