You are in good company, Jeff, reading all the bug reports about this.
It's not a bug, it's an important security feature. What they have done
is isolated JavaScript from the signed capabilities of an applet. No
JavaScript on a page can direct an applet to do anything that it can do
ONLY because it is signed. Strangely enough, though, if the JavaScript
creates a whole new applet, with the load command part of the
construction process, as I do on that page with the prompt, then, (what
do you know?) the new applet can operate in a signed mode, as directed
by the JavaScript.
To say again:
1) JavaScript cannot script an applet to do any signing-required process.
2) JavaScript can create applet instances on the fly, and if in doing so
the (new) applet is directed to do something that requires signing, it's
not a problem.
This certainly makes no sense to me. But it does provide an option that
allows loading of files from any site into Jmol. Instead of
jmolScript('load "=blu"')
you need
create-a-new-applet-and-run-the-script('load "=1blu"')
That's what my code does on that page. First, I create a div containing
the applet. Then, to load a new file, I create code for a whole new
applet using jmolSetDocument(0), and place it in that div. The new
applet "appears" instantly, loads the file, and the effect is that the
user sees just what you might expect them to -- a new model loaded.
Quite a hack, really.
Bob
