Hello,

I'm having trouble removing a series of images from a slideshow album in iPhoto using both AppleScript and Scripting Bridge. I decided that Scripting Bridge is much easier to use, so I will focus on it. But if you have a solution in either metaphor that would be great.

What I've done is just create a static array of image names that I then loop through and remove those images in the slideshow album that have the same name/title as those images within the array. But it looks like when I remove the image from the slideshow album it only ever removes the first currently selected image. Nothing else is removed, and the following error is spat to the console:

2008-11-21 04:22:19.859 MyScriptBridge[2792:813] Apple event returned an error. Event = 'iPho'\'isal'{ '----':'obj '{ 'want':'ipmr', 'from':'obj '{ 'want':'ipal', 'from':'null'(), 'form':'name', 'seld':'utxt'("Jury66_Proj1 Slideshow") }, 'form':'name', 'seld':'utxt'("000002.jpg") } }
Error info = {
ErrorNumber = -1728;
ErrorOffendingObject = <IPhotoPhoto @0x192440: IPhotoPhoto "000002.jpg" of IPhotoAlbum "Jury66_Proj1 Slideshow" of application "iPhoto" (146)>;
}

Here's some sample code:

- (id) init;

{

[super init];

iPhoto = [SBApplication applicationWithBundleIdentifier:@"com.apple.iPhoto"];

return self;

}

- (void) removeSlideshowImages:(id)sender;

{

NSMutableArray *xmlPhotoTitles = [[NSMutableArray alloc] initWithObjects:

@"000001.jpg", @"000002.jpg", @"000003.jpg", @"000004.jpg", @"000005.jpg", nil];

[iPhoto activate];

SBElementArray *albums = [iPhoto albums];

iPhotoAlbum *slideshowAlbum = [albums objectWithName:@"Jury66_Proj1 Slideshow"];

[slideshowAlbum select];

SBElementArray *albumPhotos = [slideshowAlbum photos];

for (NSString *photoTitle in xmlPhotoTitles) {

iPhotoPhoto *photo = (iPhotoPhoto *)[albumPhotos objectWithName:photoTitle];

[photo select];

[photo removeFrom:albumPhotos];

}

[xmlPhotoTitles release];

}

It almost looks like removing the image causes references to be shuffled around, causing the program to dereference a non-existent object.

BTW, I have all 5 images in the slideshow described in the xmlPhotoTitles array.

Does anyone know how to get around this?

Best,

dalmazio
