It might have to do with the new initialization system in CMS 6. If you debug, what is it that is null? Which version of PTB are you using?
Thank you for your reply!
I tried both with 1.1 and 1.2 beta.
This happend in the constructor of the provider. I couldn't debug the code so I moved the constructor code into the method that used the initialized variables instead and there it worked. So problem solved.
Hi Jonas,
I've got the same issue and I cannot debug either. Could you please explain in more details the solution you found for "moving the constructor code into the method that used the initialized variables instead".....
Thanks,
Bahar
Also in my case I'm not migrating from 5 to 6. I'm already on 6 and using page type builder but just trying to add a custom UrlRewiteProvider mainly for rewriting the EPiServer Community based page urls to a SEO friendly urls.
My costomized URL rewriter that worked in CMS 5 don't work after upgrade to CMS 6.
It seems that I can't use PageTypeBulder. I get the following exception stack trace when I try to use a typed PageData object

Do I have to write the FriendlyUrlRewriteProvider in another way in CMS 6?
