[mcclim-devel] Newbie problems with "accepting-values" / no method for CLIM:STREAM-CURSOR-POSITION

[Andy Hefner]

Looking at your backtrace, it appears that accepting-values is being
called on a stream from SLIME rather than a CLIM stream, so naturally
there are no applicable methods. CLIM usually binds *standard-input* 
and *standard-output* to reasonable defaults (see
frame-standard-input, frame-standard-output which make this choice). I
don't know why that isn't happening here without seeing your code,
maybe it is running in an unusual context (like before the frame
toplevel binds those stream variables, or in an event handler). In any
case, all you need to do is obtain the appropriate CLIM streams (via
any of frame-standard-input, get-frame-pane, etc) for your window and
write to those.
