Ugghh.. posted this too soon. Discovered my problem. I was accidently returning nil from a controller action will result in the message: *NoMethodError: undefined method `each' for nil:NilClass*
since it sets the body to the output of the action, and it puts the body directly into the rack_response Seems like a fairly unhelpful error message when returning nil from a controller. This will easily happen if someone adds a log statement or something to the end of the action expecting it to work like rails and render anyways. Might be worth adding a message at the end of the merb_controller to check for nil, and throw a proper exception with a message that the action returned no output for the controller Jacques Crocker wrote: > Looks like there's a bit of a problem rendering template's in Merb > 1.0.8.x.
