I'm testing 2.2a1. I have some ZClasses which work fine in 2.1.6. I copied my Data.fs to the new 2.2a1 install. As a non-superuser I have taken ownership of the top level of the site. When I try to access a zclass instance which uses manage_tabs in it's index_html method, I get the traceback shown below. The relevant code is checking that the containerbase is not the accessedbase whatever they are! If I take out manage_tabs from the offending ZClass index_html method, I can view index_html (but of course, I can't use the management stuff built in! making it rather useless), so that's where we're getting into trouble for sure. I've tried starting out with a vanilla 2.2a1 Data.fs and importing all the zclasses and the relevent folders - no difference. Anyone else seeing this? Is this worthy of the collector?
