Error 1023 as3-signals-v0.9-BETA

[Chetan Sachdev]

I am using as3-signals-v0.9-BETA in a simple slide application. In my signal handler, I am dispatching the same signal again based on some conditions. The application throws an exception after a couple of hours on the signals dispatch method. Below is a stack trace:

Error: Error #1023: Stack overflow occurred.

Method:

mysignal.add(mySignalHandler);

function mySignalHandler():void

{

    if(condition)

    {

       // do something here..

    }

    else

    {

        mysignal.dispatch();

    }

}

Can some one point me, what is wrong. When I am dispatching from the signal handler, is the stack getting created ? (I am not calling the method directly, I am dispatching a signal).

application throws an exception after a couple of hours 

I would suspect that the GC has collected on the listener[1]. Does this show in any other way, rather than waiting for a couple of hours?

In case GC garbage collected the listener, how would a Stackoverflow error happen. A stack should be created when I directly call the method, now in my case, I am calling it from the signal object. Now, I am experimenting with removing all listener, adding again and then dispatching. Is it fine to dispatch the event from the event handler ?
