method or propertey "addEventListener" not found

Hi there,

we got a strange problem:

I create an empty analysis and execute it (via SAP NetWeaver 7.3 SP10).

The used browser is IE 11.

When running the analysis (over NetWeaver) with default settings, everything is fine.

When we set the IE11 to compatibility mode to to IE8, the console give us the following error:


"Object or method addEventListener not found"

When running the analysis over localhost, and then switch to IE8 compatibility mode, it's working!

The questions are:

1. Why does it work on localhost, but not on NetWeaver?

2. Why does design studio try to use addEventListener when it's IE8? This method doesn't exist in IE8 and attachEvent should be used instead.

Many thanks,

    localhost does not run in an iView like on NetWeaver. This may explain the different behavior.

    Most importantly however, is that the Product Availability Matrix says on Page 8 for client:

    Prerequisites for the Design Studio Client It is required to have Microsoft Internet Explorer 9.x, 10.x or 11.x installed on the client.

    IE 8.x is supported for runtime, but see Note 1855350 and 1768161 (page 29) -- These notes are very old (2013 for DS 1.1) but list out many restrictions. I'd imagine it's only gotten more restrictive since 1.5 maybe?

    Restrictions in latter note, do any of these apply to your DS App, perhaps?

    Edit: Removed note contents, can't remember if that's allowed here, but read the second note!
