I developed a document-based application that uses basic data. When I launch the application, usually by double-clicking on it, it works fine, and I can create several data files with it. Then I close the application and try to open the file that I just created through the application, but I get a window that says: the document "data.hso" cannot be opened. MyApp cannot open files of this type.
I modified the plist file to include document types. As a resource, I used:

Delete files on Cocoa dock icon
I am really desperate at this moment, because I really can’t figure out why it should not work.
Any help is appreciated!
EDIT 1: here is a snapshot of my layer
Perhaps the application delegate should implement - (void)application:(NSApplication *)sender openFiles:(NSArray *)filenames
- (void)application:(NSApplication *)sender openFiles:(NSArray *)filenames
