Good day,

I just signed up to the mailing list, though I have been a very happy =
user of Cordova for a while now. I am working on a plugin for Cordova, =
and have thus far developed on iOS, and everything is fine. I started a =
new project with Cordova OS X, and ported some code over. But it was not =
working right. Took a long while to figure out what was happening. The =
iOS version has support for passing ArrayBuffer objects from the JS to =
native side (as NSData). This is a _very_ useful feature. So I had =
assumed it would work with the OS X version. I was wrong of course.

I tracked it down to this code in CDVBridge.m:

- (NSArray WebScriptObject*)webScriptObject
{
    // Assumption: webScriptObject has already been tested using =
isArray:
   =20
    NSUInteger count =3D [[webScriptObject valueForKey:@"length"] =
integerValue];
    NSMutableArray *a =3D [NSMutableArray array];
    for (unsigned i =3D 0; i < count; i++) {
        id item =3D [webScriptObject webScriptValueAtIndex:i];
        if ([item isKindOfClass:[WebScriptObject class]]) {
            if ([self isArray:item]) {
                [a addObject:[self =
convertWebScriptObjectToNSArray:item]];
            } else if ([self isDictionary:item]) {
                [a addObject:[self =
convertWebScriptObjectToNSDictionary:item]];
            };
        } else {
            [a addObject:item];
        }
    }
   =20
    return a;
}

The ArrayBuffer object isKindOfClass WebScriptObject, but it is neither =
an Array or a Dictionary, so it gets dropped here.

Any chance on a patch to make this work? I am a programmer, but not =
familiar enough with the Cordova internals and/or the WebScript area to =
know the proper check and conversion to put here.

Thank you,
Tyler=
