Description Tomas Zezula 2009-12-07 09:53:17 UTC
Run attached test, it fails.
Run it again with commented line 69. It passes.
Seems as a caching problem.

The layer definition is wrong. It can be fixed in three ways:

1. instanceOf attribute shall enumeration all superclasses
2. instanceOf attribute shall be renamed to instanceClass
3. instanceOf attribute can be deleted

As instanceOf attribute exists only for like-to-be historical reasons I suggest to use #2.

I admit there is some inconsistency in InstanceDataObject vs. FolderLookup behavior, but the root cause is that InstanceDataObject provides incorrect answers (due to wrong instanceOf content). Fixing this in lookup seems like P4 to me.
