Persistent Symbols not working in IE9 and IE10

(Nigel) #1

Hi. We use HYPE on a daily basis, creating many different web experiences for internal communications for large blue chip clients. Many of these clients’ employees still use older browsers like IE9 and IE10. HYPE has been great at being backwards compatible with these browsers (but work fine in IE11, and webkit based browsers), however I have noticed that persistent symbols do not work in these browsers. The developer tools show an error “Unable to get property ‘appendChild’ of undefined or null reference”.

A fix for this would be greatly appreciated.

Many thanks

I can reproduce this – to get these working in IE 9 / IE 10 until we can address this issue, I recommend putting this in the <head> of the HTML page:

<meta http-equiv="X-UA-Compatible" content="IE=8" />

(You can replace the word ‘edge’ with 8)

Thanks. That helps when we are hosting. But when embedding on pages such as intranets we can’t control that.
