非常に激しくクラッシュするため、Adobe AIR アプリケーションのデバッグに手こずっています。AIR 3.5、3.7、および AIR 3.8 ベータ版でアプリがクラッシュするポイントを少なくとも 1 つ突き止めて数日後 (ご覧のとおり、試してみました...)。
AIR 3.5 は、最終的に次のトレース出力を報告します。
ScrollerTouch.onTargetMouseDown()-F true // A
ScrollerTouch.onTargetMouseDown()-I // B
targetV [object ScrollPane] // C
CRASH! // D
Exception fault: ReferenceError: Error #1065: Variable ::_fileSystemType is not defined.
at global/trace()[int:49]
at de.superclass.control::ScrollerTouch/onTargetMouseDown()[/path/to/.../ScrollerTouch.as:381]
at de.superclass.control::ScrollerTouch/onTargetMouseDown()
ActionScript コードの抜粋:
trace("ScrollerTouch.onTargetMouseDown()-F", _scrollHorizontal ); // A
switch ( _scrollPolicyVertical )
{
case ScrollPolicy.ON:
trace("ScrollerTouch.onTargetMouseDown()-G");
_scrollVertical = true;
break;
case ScrollPolicy.OFF:
trace("ScrollerTouch.onTargetMouseDown()-H");
_scrollVertical = false;
break;
case ScrollPolicy.AUTO:
trace("ScrollerTouch.onTargetMouseDown()-I"); // B
default:
trace( "targetV", targetV ); // C
try
{
trace( "targetV.height", targetV.height );
}
catch( e: Error )
{
trace( "CRASH!" ); // D
}
// line 381 throws the hard crash:
_scrollVertical = Boolean( targetV.height < targetV.contentHeight );
trace( "targetV.xxx" );
trace( "targetV.contentHeight", targetV.contentHeight );
return;
}
そのため、381 行目で targetV.height にアクセスすると、何らかの理由で非常に激しくクラッシュします (アプリが終了します) が、その理由はわかりません。実際、このコードは長い間機能していました...
追加情報：
コードを再度変更しましたが、アプリがクラッシュし続けます。これは XCode-Console が言うことです:

これは、特定の表示オブジェクトに触れて少し移動するとすぐに発生します。このオブジェクトは、マウス イベント DOWN をリッスンし、MOVE でコンテンツをドラッグします。イベントシステムとか関係あると思います。しかし、私は完全に盲目だと思います。
最初の質問: ::_fileSystemType とは何ですか?
クラッシュログと XCode コンソールの出力が何を意味するのか、誰が知っているでしょうか?
