I deleted my last comment by accident (as it appeared twice in the history), so here it is again for completeness:Hi MC Stuff,you pointed me into the right direction of using a Servlet Filter. By paying closer attention to the Stacktrace in case of an Exception I realized the class com.day.cq.wcm.core.impl.WCMDeveloperModeFilter being involved.By searching the internet I found out that the ACS Commons Project actually solved the "gentle degeneration" issue already on a Component level for the va...
