[Jmol-users] window.location="some URL" breaks Jmol viewer

[Roberto M. <rob...@gm...>]

Dear all,

I am experiencing a strange problem with JSmol. I have a JSmol applet on my
page and a link to download the PDB file.

The link works by setting "window.location" to a php page that forces the
download of the PDB file (via headers like "Content-Disposition:
attachment; filename=...") without actually leaving the papge where the
Jmol applet is.

The problem is that the Jmol applet works perfectly before I click on the
link, and when I click there the browser dowloads the file but then the
Jmol applet freezes.

I had a look at the Javascript console and it turns out that if I try to do
anything with Jmol after clicking on the link to download the PDB file I
get a long list of errors:


Uncaught TypeError: Cannot read property 'viewer' of null
JSmol.min.nojq.js:80
g._processEvent JSmol.min.nojq.js:80
(anonymous function) JSmol.min.nojq.js:55
p.event.special.(anonymous function).handle jquery-1.8.2.min.js:2
p.event.dispatch jquery-1.8.2.min.js:2
g.handle.h


Any ides of why it is so? Am I doing something wrong?

Let me know.

Best,
Roberto
