FLEX - Problem with the released version

michael_fallenbchel — Tue, 19 Jun 2012 12:47:22 GMT

Hi experts,

I've created a FLEX-project. Everything's working fine - until my actual "version".

I have added some libs (alivePDF, bulkloader, fzip) to my application, which is working fine in the debug version. I have exported a release version, which is working fine in some SWF-Debugger (SWiX), too.

Now I have imported it to SAP (as before with the previous versions), but my new added functions only show this problem:

TypeError: Error #1009: Der Zugriff auf eine Eigenschaft oder eine Methode eines null-Objektverweises ist nicht möglich.

at MethodInfo-856()

at flash.events::EventDispatcher/dispatchEventFunction()

at flash.events::EventDispatcher/dispatchEvent()

at br.com.stimuli.loading::BulkLoader/_onAllLoaded()

at br.com.stimuli.loading::BulkLoader/_onItemComplete()

at flash.events::EventDispatcher/dispatchEventFunction()

at flash.events::EventDispatcher/dispatchEvent()

at br.com.stimuli.loading.loadingtypes::LoadingItem/onCompleteHandler()

at br.com.stimuli.loading.loadingtypes::ImageItem/onCompleteHandler()

Sorry for the German version, should be "Error #1009:Cannot access a property or method of a null object reference."

Does anyone know what can be the problem?

Thanks

Michael

Hi,

Imported to SAP? - I cannot understand this statement.. Do you have an HTML wrapping the SWF?

Also, it seems your onCompleteHandler is trying to use and access properties of a null object. When you work with Events you must ensure your handler will be in a usable state when you dispatch the event.

Maybe if you provide parts of the code where the issue happens others may help..

I created a release version of my project in FLEX. Then I created a BSP application and imported all the "release" files as MIME.

Everything is working fine in my debug version, I'm quite sure the problem is with the bulkloader lib.

Here's the coding for it:

BulkLoader.removeAllLoaders()

var loaderbulk: BulkLoader = new BulkLoader("pdf");

loaderbulk.add( String(xmlDetail.PIC_APPL) , {id:"APPL", type:BulkLoader.TYPE_IMAGE});

loaderbulk.add( String(xmlDetail.PIC_EINZ) , {id:"SING", type:BulkLoader.TYPE_IMAGE});

loaderbulk.add( String(xmlDetail.PIC_PACK) , {id:"PACK", type:BulkLoader.TYPE_IMAGE});

loaderbulk.add( barcode , {id:"BARCODE", type:BulkLoader.TYPE_IMAGE});

loaderbulk.addEventListener(BulkLoader.COMPLETE, onComplete);

loaderbulk.start();

function onComplete(evt : Event) : void{

//var image1:Image = new Image;

var myBmpData:BitmapData;

var myByteArray:ByteArray;;

var bmp:Bitmap;

var encoder:JPEGEncoder = new JPEGEncoder ( 100 );

var bytes:ByteArray;

myByteArray = new ByteArray;

bmp = loaderbulk.getBitmap("APPL");

myBmpData = bmp.bitmapData;

myByteArray = bmp.bitmapData.getPixels(myBmpData.rect);

bytes = encoder.encode ( myBmpData );

myPDF.addImageStream( bytes, ColorSpace.DEVICE_RGB, null,15,30,30 );

myByteArray = new ByteArray;

bmp = loaderbulk.getBitmap("SING");

myBmpData = bmp.bitmapData;

myByteArray = bmp.bitmapData.getPixels(myBmpData.rect);

bytes = encoder.encode ( myBmpData );

myPDF.addImageStream( bytes, ColorSpace.DEVICE_RGB, null,80,30,30 );

myByteArray = new ByteArray;

bmp = loaderbulk.getBitmap("PACK");

myBmpData = bmp.bitmapData;

myByteArray = bmp.bitmapData.getPixels(myBmpData.rect);

bytes = encoder.encode ( myBmpData );

myPDF.addImageStream( bytes, ColorSpace.DEVICE_RGB, null,145,30,30 );

myByteArray = new ByteArray;

bmp = loaderbulk.getBitmap("BARCODE");

myBmpData = bmp.bitmapData;

myByteArray = bmp.bitmapData.getPixels(myBmpData.rect);

bytes = encoder.encode ( myBmpData );

myPDF.addImageStream( bytes, ColorSpace.DEVICE_RGB, new Resize ( Mode.NONE, null ),340,110,50 );

Alert.show("Do you want to save?","Save",Alert.YES | Alert.NO ,SINGLE_BLOCK,handleAlert,null)

}
