Problem with EPiServer 8 upgrade


I tried the preview upgrade on a project with the SiteSeeker module on it yesterday and most of it did go well but I have one problem that I can't figure out what it is.

We have this class

public class IntraSiteSeekerConfiguration : EPiServerSiteSeekerConfiguration
        public CustomerSiteSeekerConfiguration()
            : base(new SiteSeekerServiceOverride(), 
                   new SiteSeekerServiceOverride())

And the baseClass looks like this:

public class EPiServerSiteSeekerConfiguration : SiteSeekerConfiguration
        public EPiServerSiteSeekerConfiguration(params SiteSeekerServiceOverride[] serviceOverrides);

The error we get is this: (sorry for the swedish in the message)

[NullReferenceException: Objektreferensen har inte angetts till en instans av ett objekt.]

Anyone got any clue?

Peek into ConfigureEPiServerVersionSpecificOverrides(), I'd guess there's some hard coded stuff not handling v8 in there.

Did you upgrade SiteSeeker module at the same time? We saw some problems with that:

Thanks Johan.

I talked to the support for SiteSeeker and they have confirmed that it is a bug that the integration module tries to load a support module that have no version that support version eight yet.

They are working on it

Tjenare Henrik

Jag får något liknande fel. Fast mitt fel är på engelska?? Vad kan det bero på?

Säg till mig me när SiteSeeker har en fix är du snäll

Just wanted to update everyone that we now have a fix for this issue. Please contact SiteSeeker support to request it.

Best regards

Still only beta. Right? 

Apr 14, 2015 16:53

Yes, we have an internal discussion around this and will update the thread if anything changes.

Is 4.2.9251-beta the latest version? Got it 1/4 from Siteseeker support.

I still got the problem with that version and Episerver version

Update: got feedback from Siteseeker support again: apparently something wrong with the package, so they mailed me som new DLLs and with them it works with Episerver v8.5.0.0
