I'm trying to add a couple of extra DB fields to page comments, but I've got totally stuck with the error from the title. Code in questions is:

class OurPageComment extends PageComment {
static $db = array(
"Company" => "Varchar(100)",
"Email" => "Varchar(255)",
"Homepage" => "Varchar(255)",

As you can see I've just tried extending PageComment the same way it's done with other classes in tutorials/docs, but it obviously can't be done that way.

Error trace (when I go to /db/build/..):

* Bad class to singleton() - OurPageComment

Ok, I managed to solve the problem, the class that extends PageComment has to be in a separate file. I had it defined in the same file where my page class is defined and SS couldn't find it there obviously.
