Adoe AIR Issue

[VidhyaHere]

I have an Adobe AIR application with a chart component displaying some online data. The chart component has to display a bunch of parameters about 10 of them. The application has a timer to display current system time.

The chart component is invoked from the timer(using a bindable object) as shown below. A separate bindable object is used to prevent delay in timer.

private function onTimerEvent(event:TimerEvent):void

{
//Update time in screen

oCurrDate = new Date(); 

curTime = oDateformatter.format(oCurrDate).toString(); 

oCurrDate = null;  

//oUpdate- Bindable object to inform chart about update 

//Call chart every 250 ms 

oUpdate.bUpdate = !oUpdate.bUpdate;  

}

Iam using a calllater function in chart's update event as shown below. updateParameter() will update the dataprovider of each of the parameter and draws it.

public function onUpdateEvent(evt:PropertyChangeEvent):void {

//aPlotIndex set to 0 for first parameter  

aPlotIndex.push(0);  

this.callLater(updateParameter, aPlotIndex);  

}

The problem is the timer and chart updation stops after running 20 to 21 days. After 20 or 21 days, the update happens only on mouse move. When I moved mouse the time displayed & data in chart are updated.

I profiled the application and found that there is no memory leakage issues. I am logging all the errors but I didn't get any error in the log also. Everything seems weird.

1. Is it because of using the calllater function.
2. Is it that the timer is still running but frame update not happening.

I am using Flex SDK3.3 and Flex AIR version 2.0.4.13090.

Please guide me to resolve this issue.

Are you using getTimer() or other relative timing functions? I did a quick calculation: The maximum value for an integer in AS3 is 2,147,483,647. getTimer() returns milliseconds passed since program start as an int. For 21 days that would be 1,814,400,000. So if you are just estimating and it were a couple of days more, you have an integer overflow.

In any case I would try to remove references to absolute numbers (if any) and base calculations on relative values only, for example using Event.ENTER_FRAME or TweenMax.delayedCall

Hi Ruben,

Thank you for your reply.

We are using timers. I have noticed this reset counter in the AS Timer class.

So what we did was after 36 hours, the timer is stopped, reset and again started.

The system is running for the past 10 days.

Let me check it for few more days and I will send you an update for sure.

Best Regards,

The system again stopped after 22 days.

In the current implementation after some interval, we stopped the timer, reset it and again started.

But still the same conditions are repeated. The frame update happens only on mouse move.

Is this have anything to do with frame update rate.

Please provide your valuable suggestions.

Thansk & Regards,
