Difference between 3.1 and 4.2 for object's implementation in oldcore.

kgardas

Hello,

I'm trying to update our semantic extension for xwiki from 3.1 to 4.2 to
be able to release this as an open-source finally. Now, it looks like
something inbetween 3.1 and 4.2 changed in xwiki-platform-oldcore's
com.xpn.xwiki.objects* since my current 4.2 setup complains a lot with a
message like:

Wrapped Exception: Error number 7006 in 7: Cannot find property class
com.xpn.xwiki.objects.classes.SPARQListClass in MetaClass object

The SPARQListClass is our implementation of the list class which
provides dynamic list based on the supplied SPARQ query and which was of
course working well on top of 3.1. I'm looking into all the classes in
4.2's com.xpn.xwiki.objects subdirectory but so far I'm not able to
distill what change between 3.1 and 4.2 breaks our SPARQList.

Any idea what's going wrong or where should I have a look is highly
appreciated.

Thanks!
Karel
