Compatibility mode and Embedded interfaces

Question

Hello:

I am facing an error with embedded interfaces using IE11 and compatibility mode, using Appian 16.2.

In tempo.nocache.js:
Error: "'HTMLDivElement' is undefined"

While debugger highlights the following code:
(Line 49:) if(HTMLDivElement)

In this thread, the poster also had to turn off compatibility mode to get the embedded interface to work:

Accessing the html in IE11 without compatibility mode or in Chrome works correctly.

This is mostly a browser quirk specific to IE version < 11.
IE has many quirks when it comes to JavaScript - and this applies specifically to IE7, IE8, IE9.
Things got better from IE10.
And IE11 confirms to the JavaScript implementation of other browsers like Chrome and Firefox.

Embedded interfaces require JavaScript and Ajax. And the behavior of JS is affected by browser quirks,
In compatibility mode, IE emulates the older versions and hence you may be getting that error.
In no compatibility mode, its purely IE11, and IE11 does not have as many quirks as the older versions - IE11 mostly confirms to the JS behavior of other browsers.

So, I don't think we can do much about it.
