[elephant-devel] unable to use persistent-class

[Aycan iRiCAN]

Thank you,

I opened the store before my class declaration. Could this be changed
in the future? Why we need to open the store first?

Now I have another problem. I have a web action that handles a form
post. This action creates an instace of content class and fills the
data slot.

Since I am using utf-8 encoding with sbcl, when I list the content
instances with a web page, I'm having strange characters from data
slot.

Is there any problem with utf-8? I didn't tried to persist the
instance yet. Just created an instance and read back from it.

Best Regards.
