The amazing repeating event!

Yes. But that interval is turned on and set to fire every five seconds as soon as I create my NetConnection object. The two second interval is to establish a check on the result from the call to the server; I want to check that once, and only once, two seconds after making each call to the server.

Anyway, one of my colleagues just figured out my problem. It was in the definition of ESMSIsConnected. I changed it to

var ESMSIsConnected = new Object();
ESMSIsConnected.onResult = function(returnValue)
{
_root.application.EventDesktop.m_ConnectionTestResult = true;
}

and put it in ConnectionTest(), and changed the call to the server:

m_connection.call( "heartbeat" , ESMSIsConnected);

It works now.

Thanks for your help.

_root.application.EventDesktop.m_ConnectionTestResultID = setInterval(_root.application.EventDesktop.ConnectionTestResult, 2000);

So, you're setting an interval to call _root.application.EventDesktop.ConnectionTestResult every 2 seconds.

Dont you want the interval to call ConnectionTest() ?

I only clear the interval for ConnectionTest when I have intentionally closed the NetConnection object. The idea is to detect when the connection drops out, and then to detect when it is available again. It may be that when it drops out I have to switch to attempting a reconnection, and finally failing after some number of tries or a specified timeframe.

I clear the interval to ConnectionTestResult every time it fires:

public function ConnectionTestResult ()
{
clearInterval(_root.application.EventDesktop.m_ConnectionTestResultID);
if (_root.application.EventDesktop.m_ConnectionTestResult != true) {
_root.application.EventDesktop.setTitleBar("Lost heartbeat");
}
else
{
_root.application.EventDesktop.setTitleBar("ConnectionTestResult returns TRUE");
}
}

but, this is kind of irrelavent since it's interval is reset when the heartbeat call is made. Since that timer is never canceled (as long as the NetConnection object is alive,) it just keeps firing.

But here's the thing. m_ConnectionTestResult is only set to true when main makes the callback to ESMSIsConnected. Just before the call to main is made,
m_ConnectionTestResult is set to false. If ESMSIsConnected doesn't execute, m_ConnectionTestResult cannot become true. This makes no sense.

Here are the two complete functions:

private function ConnectionTest ()
{
_root.application.EventDesktop.m_ConnectionTestResult = false;

//Response function for the heartbeat call
var ESMSIsConnected = function( )
{
_root.application.EventDesktop.setTitleBar("ESMSIsConnected fired!!!");
_root.application.EventDesktop.m_ConnectionTestResult = true;
}

if (_root.session.flashComm.m_connection == null)
{
_root.application.EventDesktop.m_tries++;
_root.application.EventDesktop.setTitleBar("Lost connection " + _root.application.EventDesktop.m_tries + " failures");
}
else
{
_root.application.EventDesktop.m_tries = 0;
_root.session.flashComm.m_connection.call( "heartbeat" , new ESMSIsConnected());
}
_root.application.EventDesktop.m_ConnectionTestResultID = setInterval(_root.application.EventDesktop.ConnectionTestResult, 2000);
}


public function ConnectionTestResult ()
{
clearInterval(_root.application.EventDesktop.m_ConnectionTestResultID);
if (_root.application.EventDesktop.m_ConnectionTestResult != true) {
_root.application.EventDesktop.setTitleBar("Lost heartbeat");
}
else
{
_root.application.EventDesktop.setTitleBar("ConnectionTestResult returns TRUE");
}
}

Where in your code are you clearing the interval? I don't see it there.

Looking at this line:

_root.application.EventDesktop.m_ConnectionTestResultID = setInterval(_root.application.EventDesktop.ConnectionTestResult, 2000);

In the rest of your code, _root.application.EventDesktop.ConnectionTestResult is a boolean variable, but you're setting an interval on it like it's a function.

Actually, it seems the variable is named _root.application.EventDesktop. m_ConnectionTestResult , so I'm not entirely sure why the function is running at all. Is there other code related to what you've posted above that might be calling ConnectionTest();
