Did something change in Modeler 8.x w/ how redirects happen in request handlers? I used to be able to use the following code in 7.x but in 8 it just stays at the url of the request handler being called. // Redirect to home page Core.execute(mSession.createContext(), "System.ShowHomePage"); // Redirect to login page response.setStatus(IMxRuntimeResponse.SEE_OTHER); response.addHeader("location", "index.html");
