Yeah, that sucks. Debugging in older versions of IE is pretty awful.
Ah! I think I just found your answer. Look at the comments in the
_oncompleted method of RequestQueue:
/**
* Listens for the "completed" event of the transport object and
decreases
* the counter for active requests.
*
* @param e {qx.event.type.Event} event object
* @return {void}
*/
_oncompleted : function(e)
{
if (qx.core.Variant.isSet("qx.debug", "on"))
{
if (qx.core.Setting.get("qx.ioRemoteDebug"))
{
if (e.getTarget()._counted)
{
this.__activeCount--;
this.debug("ActiveCount: " + this.__activeCount);
}
}
}
// delegate the event to the handler method of the request depending
// on the current type of the event ( completed|aborted|timeout|failed
)
var request = e.getTarget().getRequest();
var requestHandler = "_on" + e.getType();
// It's possible that the request handler can fail, possibly due to
// being sent garbage data. We want to prevent that from crashing
// the program, but instead display an error, and, importantly
// (regardless of error) remove the request from the queue.
try
{
if (request[requestHandler])
{
request[requestHandler](e);
}
}
catch(ex)
{
this.error("Request " + request + " handler " + requestHandler +
" threw an error: ", ex);
// Issue an "aborted" event so the application gets notified.
// If that too fails, or if there's no "aborted" handler, ignore it.
try
{
if (request["_onaborted"])
{
var event = qx.event.Registration.createEvent("aborted",
qx.event.type.Event);
request["_onaborted"](event);
}
}
catch(ex)
{
}
}
finally
{
this._remove(e.getTarget());
}
},
Note that it's issuing the "aborted" event when *the request handler* throws
an error. That's almost certainly what's happening. Try adding a try/catch
block inside of your "completed" handler, and you'll likely find the
problem.
