Error during program execution (Ch 2 Text Editor)

akumok · January 23rd, 2009, 04:46 PM

I'm working on the Text Editor example and when I try to run program in order to save new or open existing file I'm getting error

TypeError: Error #1034: Type Coercion failed: cannot convert flash.events::Event@8b4d971 to mx.events.FileEvent.

I'm not working in Air SDK, instead I'm using Flex Builder 3

Any ideas? Thanks

As I find out from source code it was an error in the book.

Instead of

Code:

private function onFileOpenSelect( event: FileEvent) : void
{
                currentFile = event.file as File;
                openFile();
}

should be

Code:

private function onFileOpenSelect( event: Event) : void
{
                currentFile = event.target as File;
                openFile();
}

and instead of

Code:

        
private function onFileSaveSelect( event: FileEvent) : void
{
                currentFile = event.file as File;
                textChanged = false;
                title = "Text Editor - " + currentFile.name;
                saveFile();
}

should be

Code:

        
private function onFileSaveSelect( event: Event) : void
{
                currentFile = event.target as File;
                textChanged = false;
                title = "Text Editor - " + currentFile.name;
                saveFile();
}

I'm submitting this for Errata as an error if someone here at Wrox care about it. Thanks
