Here's a quickfix for that - first the code, this is from webrick's httpstatus class: The quickfix is attached to the first list entry in the hash: And previewing the fix shows the following proposed edit: As usual, the NetBeans Ruby forums can be accessed via Nabble here and Gmane newsreaders here (other feedback channels here).
