Hi there, I am using a custom login button to log users in with a Microflow that executes a login Java action. The login works fine and logs the user in correctly BUT when logging in using Firefox, a pop-up briefly shows "An error has occured..." and goes away but the login is still successful. After checking the Firefox console the only relevant thing I can find is the line : {message: "Unable to load http://localhost:8082/xas/#executeaction status: 0", stack: ".cache["dojo/errors/create"]/</</_30e@http://localhost:8082/mxclientsystem/mxui/mxui.js:16_4f4@http://localhost:8082/mxclientsystem/mxui/mxui.js:16", response: Object, status: 0, responseText: "", xhr: XMLHttpRequest} This line is repeated once right afterthe first one. There is nothing in the Mendix console and this problem only happens with Firefox. Any ideas?
