Appex problem with IE11

Maarten,

I successfully retested our EventSource demo in vw8.0.1 and  IE11. The server was on Windows 7.
Could you load AppeX-Examples and run Event-Source demo? It would be interesting to know if you can run it.

Maybe the problem is the drawbacks of the MS implementation of the event handler as described in this article:

http://www.quirksmode.org/js/events_advanced.html

That notably states:


1. The event handling function is referenced, not copied, so the thiskeyword <http://www.quirksmode.org/js/this.html>  always refers to the window and is completely useless.


where our Appex JavascriptClass states:

addEventListener(type, listener, useCapture) {
// Simulate the EventTarget API


return this.eventTarget().addEventListener(type, listener, useCapture || false);
}

@+Maarten,

Hi,

I have a problem that only arises in IE shown here in what appears to be in Cincoms Appex Core.js.

Any ideas ??

Jerry and Tamara,

 

Please find enclosed 2 videos.

 

The first one is on Windows 7, actually the event-source demo works but only if I hit the refresh button otherwise the page stays white.

 

The second one starts on Mac creating a new image with the example and running it through Chrome all is oké. I then switch to Windows 8.1 on virtual box opening the same image that just worked on OSX.

You can see the result is blank page first then an error when hitting refresh.

Maarten, what do you see in the ‘Network’ tab when loading the example? You should see a bunch of _appex_postClientEvent requests, then _appex_getServerEvents?sessionId=…., and then message-event?sessionId=… . Do they return at all, are they just waiting for a response? That’s what it kind of should look like - an EventStream keeps the connection open and just keeps reading event messages from it.

IE is notoriously non-compliant with specifications, and doesn’t have native support for EventStream - all the other mainstram browsers do. AppeX contains an EventStream emulator for IE that we have tested in our environments, but we don’t know what other factors may affect its functionality.

Hi,

Sorry for late reply but actually I get blank pages when running the event source demo with IE11. 

This happens both on Windows 8.1 on Windows 7 and with both VW 8.0 and 8.01.

I completely reinstalled both 8.0 and 8.01 and it happens in a vanilla image loading Appex tools, Sioux Tools and the examples.

This is what I see on Windows 8.1

And on windows 7

Notice that the following gives a white page within IE, you need to refresh to see the form ?? which is not so nice …
