Red5/Sparkweb chat echo in rooms

Hi,

since it is a Red5 Sparkweb, i’m posting it here…

I love the dark looking sparkweb, and my main problem is that in rooms, everything i type is getting echoed.

Example:

XY: test 01:00 am

Me: test 01:00 am

test 01:00 am

Since I am only typing it once, where does it comes from? Anyone had this?

Update:

Figured out that if client(Spark) is running besides webmessenger this happens. Ressource is in both clients unique. Dont know why that happens.
