Summary: jsvApplet._applet remains null after Jmol.getJSVApplet
Initial Comment:
Trying to get JSpecView and Jmol to interact using the new JavaScripts, I'm
unable to get jspecView to show and load data.
Here's a short summary of what I do:
<script type="text/javascript" src="jmol/jquery-1.8.2.min.js"></script>
<script type="text/javascript" src="jmol/JmolCore.js"></script>
<script type="text/javascript" src="jmol/JmolApplet.js"></script>
<script type="text/javascript" src="jmol/JmolControls.js"></script>
<script type="text/javascript" src="jmol/JmolApi.js"></script>
<script type="text/javascript" src="jmol/JmolJSV.js"></script>
//init Jmol
var jmolInfo = {width : 370, height : 370, jarPath : 'jmol', jarFile :
'JmolApplet.jar', };
jmol = Jmol.getApplet('jmol', jmolInfo);
Jmol.script(jmol, 'load DATA \'inline\'\n ... snipped ... \nEND \'inline\'');
//init JspecView
var jspecInfo = {width : 370, height : 370};
jspec = Jmol.getJSVApplet('jspec', jspecInfo);
Jmol.jsvLoadInline(jspec, 'DATA \'inline\'\n ... snipped ... \nEND \'inline\'');
This fails because jspec._applet is null, meaning the call to loadInLine in
JmolJSV.js#219 fails with Error calling method on NPObject.

Message:
This is not a bug. This is just not understanding how to synchronize the
loading of the two applets. Since we don't know which applet will finish
loading first, we have to issue a special command that waits for both to
load before giving a script to either:
// applet ids and commands to give only when all applets are ready;
// also sets up a script sync pathway for Jmol/JSpecView.
Jmol.setAppletSync([jsvApplet, jmolApplet], ["load acetophenone.jdx",
null], true);
Says "after these two applets are loaded, send jsvApplet its load command.
The last parameter indicates that this is a Jmol/JSpecView connection,
which is treated specially by Jmol.
