[MACTCL] Opening app by double-clicking or dragging file

[Jasper T. <ja...@si...>]

Hi MacTclers,
I have a long standing problem that if I double click a file that is handled by my app, or if I drag it to the app’s icon, I get an error message like this:

The document “posning.sml” could not be opened. Simile cannot open files in the “com.Simulistics.sml” format.

The app then opens without opening the document. However, if I do the same thing when the app is already running, the app’s tk::mac::OpenDocument procedure is called and the document opens. I also have tk::mac::OpenApplication and tk::mac::ReopenApplication defined, but neither are called in the first case.
I enabled the ‘com.apple.security.authorization.apple-events’ key when signing the code, but this does not seem to change anything.
Any help very much appreciated!
