Installscript not recognized by SmartUpdate

[SaraS]

I am attempting to download and install a small application using
SmartUpdate.

I created a JavaScript installscript based on examples from the
SmartUpdate documentation. I saved it as test.js.

I put this JavaScript into the same folder as my app file ( a .bin
encoded Mac installer )

I then ran signtool on the folder, using a command file with one line as
follows:

installscript=test.js

I can open the .jar file with ClassWrangler and see the compressed
test.js file, and if I look at the manifest, it looks like test.js has
been designated as the install script.

When I download the .jar file using a trigger script, I get a warning
telling me there is no install script in the .jar file.

Any ideas?

Thanks

A note - the install script works fine in Windows, and with Mac
Communicator 4.75, but the error I reported comes up in 4.6. I am assuming
this is a bug? Or an unimplemented feature? Anybody know?
