I also have the same error, cant fix it. It all started when i reinstalled windows and installed arcgis again. I do the topology corectly but the error inspector doesnt work, although my errors are shown
I too am having the same issue. Edit session is on for the applicable feature class. It works fine with other topologies, but not one in particular. It also shows the errors but the error inspection table is greyed out and I cannot therefore do a "search now" for the visible extent. Please advise. Thank you.
