Thanks for your review. 2009/11/15 Andrew Gierth <andrew@tao11.riddles.org.uk>: > Hi, I've started reviewing your patch. > > I've already found some things that need work: > > - missing _readWindowFrameDef function (all nodes that are output > from parse analysis must have both _read and _out functions, > otherwise views can't work) I added _outWindowFramedef() but seem to forget _read one.
