I was trying to do a simple login request and can't really figure out
how everything fits together and don't completely understand where the
problems even are. I have the following code:
(in-package :contentrees)
(defun make-main-page ()
"Lays out the main page."
(make-instance 'composite :widgets
(list
(make-instance 'login
:on-login #'check-login))))
(defun check-login (obj login-info)
(format t "~a" (email login-info)))
check-login gets called when I click on login, but then the debugger
gives me this error:
There is no applicable method for the generic function
#<STANDARD-GENERIC-FUNCTION WEBLOCKS:EMAIL (1)>
when called with arguments
(#<#:G1552 {11F61DA1}>).
[Condition of type SIMPLE-ERROR]
In the debugger, login-info appears as a standard object with email
and password properties (filled in correctly). I am just not entirely
sure how to access them - I thought I could just get to them like I do
with a CLOS object usually, but I also don't know that much about CLOS
and feel like there may be a problem with doing this across
packages.
Thanks,
Saikat
