Retrieving Objects from Sessions

ironicon has asked for the wisdom of the Perl Monks concerning the following question:

Dear monks, I stored an object in CGI::Session, upon retrieving it I want to execute a method on it. However I get the following error

Can't locate object method "display" via package 
"Digilink::Ressource" at
        ../..//Digilink/View/AddRessource.pm line 152 (#1)
    (F) You called a method correctly, and it correctly indicated a pa
+ckage
    functioning as a class, but that package doesn't define that parti
+cular
    method, nor does any of its base classes.  See perlobj.

However the object in question has a method called display, and the object Digilink::Ressource ist put in via "use" in the script (no errors there..)
Have I missed something there? Do I have to do some kind of dereferencing?
Sorry if I'm a bit vague but English is not my first language..
Peter

It looks like you need to load the Digilink::Resource module: `use Digilink::Resource;` The session module won't load it automatically, even though it can apparently thaw objects from this class. -sam	[reply] [d/l]

Can you please post the code used to store and retrieve the object? Remember to wrap it in <code> tags. Thanks!	[reply]

Thanks for your help, upon creating a short script with a testcase i fiddled around further and came up with an solution : If I call the method with `Digilink::Ressource::display($Ressource);` it works.. Sorry to have you bothered Peter	[reply] [d/l]
