I suspect the problem are these lines of code in qx.io.remote.Exchange:900
try{
this.dispatchEvent(vResponse);
} catch(ex) {
this.error("Dispatch failed", ex);
}
The event dispatch is enclosed by a try catch block, which might "eat"
your exception. What happens if you comment out the "try/catch"
statement and call dispatchEvent without it?
