[flexcoders] Error in Adobe class MultiTopicConsumer

[bbloggs96]

I am using the MultiTopicConsumer with Blaze.

I have had problems with removeSubscription, it gives me an error when
I remove the last subtopic in the array of subscriptions. It works OK
if any other subtopic is removed.

I tracked down the problem to the actual Adobe Class
MultiTopicConsumer and method removeSubscription.

The code removes the subtopic, but then does a check afterwards to see
if it is ttrying to remove a subtopic that does not exist. But when it
is the last subtopic, it always fails.

Does anybody have a work around?

This is the method from Adobe Class MultiTopicConsumer:

    public function removeSubscription(subtopic:String = null,
selector:String = null):void
    {
        for (var i:int = 0; i < subscriptions.length; i++)
        {
            var si:SubscriptionInfo =
SubscriptionInfo(subscriptions.getItemAt(i));
            if (si.subtopic == subtopic && si.selector == selector)
            {
                subscriptions.removeItemAt(i);
                break;
            }
        }
        if (i == subscriptions.length)
            throw new MessagingError("Attempt to remove a subscription
with subtopic: " + 
                subtopic + " and selector: " + selector + " that this
consumer does not have");
    }

The problem is the if (i == subscriptions.length), which always is
true because it has just been removed.
