Re: [as3-signals] Error 1023 Stack overflow with as3-signals-v0.9-BETA

[Neil Manuell]

Well, As the Signal Handler is dispatching the same Signal as it is listening too, its not really surprising that this is happening.

I imagine that the conditional is supposed to protect against this, but it is obviously at some point failing, and the condition is False twice in a row, and you are getting the StackOverFlow.

I suggest that what ever it is you are trying to do, there is probably a better and safer way of doing it.

Without more info, I can't really say more.

cheers

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).

Thanks for your answer Neil. After a couple of search, I found that there is no Async delaying, so the stack is getting created of my signal handler method. 

May I ask for a little help here.. I had explored your Finite state machine and I am looking for a Video recording of yours :) Could you share some of your presentations on Finite State Machines..

Thanks a lot in advance :)
