hello, i have a problem with my Hunchentoot application. i would like to test redirect, so i create this function :

(defun handle-redirect () (hunchentoot:redirect "/clappa/index"))

and for debugging :

CL-USER> (setf hunchentoot:*catch-errors-p* nil) NIL

so, in the browser, http://localhost/mytest/redirect i have this :

invalid number of arguments: 1 [Condition of type SB-INT:SIMPLE-PROGRAM-ERROR]

Restarts: 0: [TERMINATE-THREAD] Terminate this thread (#<THREAD "hunchentoot-worker-5" {C7572A9}>)

Backtrace: 0: ((LAMBDA (SWANK-BACKEND::DEBUGGER-LOOP-FN)) #<FUNCTION (LAMBDA #) {ADF96ED}>)

and slime is disconnected. in the buffer *slime-events* i have this :

("invalid number of arguments: 1" " [Condition of type SB-INT:SIMPLE-PROGRAM-ERROR]" nil nil) (("TERMINATE-THREAD" "Terminate this thread (#<THREAD "hunchentoot-worker-5" {C7572A9}>)")) ((0 "((LAMBDA (SWANK-BACKEND::DEBUGGER-LOOP-FN))\n #<FUNCTION (LAMBDA #) {ADF96ED}>)") (1 "(SWANK::CALL-WITH-BINDINGS\n ((*PRINT-PRETTY* .
