I have a unit test that demonstrates some inconsistent behavior with a Hash being converted to XML with the :root option. Sometimes it works fine: Hash.new.to_xml(:root => 'test') "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<test>\n</test>\n" But sometimes I get an argument error: Hash.new.to_xml(:root => 'test') ArgumentError Exception: wrong number of arguments (1 for 0) I thought it may be a bug related to the version of Rails, but I have tried several versions and have the same problem. Anyone have any ideas of where I should be looking?
Sounds to me you are including some other class that has the to_xml method somewhere. It can be either something an outdated plugin uses or some code in your lib/ folder or part of a gem. That's why it only happens "sometimes", it only happens in classes that have the non- Rails to_xml method loaded.
