Hi,
I've created a class and added a couple of properties to it via the class editor (a string and a text area). When I try to add a User list (from the drop down menu) the following exception occurs:
Error number 0 in 11: Uncaught exception
Wrapped Exception: com.xpn.xwiki.objects.meta.UsersMetaClass incompatible with com.xpn.xwiki.objects.classes.PropertyClass
com.xpn.xwiki.XWikiException: Error number 0 in 11: Uncaught exception
Wrapped Exception:

at java.lang.Thread.run(Thread.java:799)It looks to me as if UsersMetaClass.newObject(ctx) should return an instance of UsersClass (this is what StringMetaClass does for example). It also looks like GroupMetaClass does the same....
Incidently, is there a way to remove an unwanted property from the class ? During my experiment I added a DBListClass (to test this) but can't see how to remove it.
Cheers,
Dan
PS. Top job on getting b2 out :)
