Issue #1
When I copy the root of the OTrunk step, the root object is missing some
objects and content. Please see below. In this example there are two objects
that show up as <null /> in my generated otml. Also the reference to
${mw_model} is no longer valid in my generated otml because all the ids are
converted to number ids. Perhaps this problem is releated to the <null />
objects since the actual declaration of the mw_model id shows up as <null />
in my generated otml file.

Issue #2
I also get this other issue when I click on an OTrunk step in the VLE. I
receive many of these "Cannot call method "xxx" of null or undefined"
errors.
org.mozilla.javascript.EcmaError: TypeError: Cannot call method "getText" of
null (

Caused by: org.apache.bsf.BSFException: JavaScript Error: Internal Error:

)
Looking at the last error as an example, I checked the js file
http://svn.concord.org/svn/projects/tags/tels/otrunk-scripts/biologica-20071126.133236/biologica-meiosis-screen.jsand
looked at line #9 to find that the variable context is probably null
(please see below). Perhaps context is supposed to be defined by the
importPackage or importClass statements but are not performing so properly.
*first 9 lines of the js file*
importPackage(Packages.org.concord.biologica);
importPackage(Packages.org.concord.biologica.ui);
importPackage(Packages.org.concord.biologica.engine);
importPackage(Packages.java.lang);
importPackage(Packages.java.beans);
importClass(Packages.org.concord.otrunk.view.OTFolderObject);
importClass(Packages.org.concord.otrunk.ui.OTText);
var meiosisView =
context.getComponentForObject("meiosisView").getComponent(0);
How can I get rid of all these "Cannot call method "xxx" of null or
undefined" errors?
Thanks,
Geoff
