Issue #1
The <null/> is probably because your don't have the OTModelerPage in
your runtime classpath when you do the copy. There should have been an
error printed about that. In that case when the otml file is loaded in
the system doesn't know how to handle OTModelerPage so loads it in as
null instead. Then when it is copied the null is copied.
Issue #2
The context object is provided to the script automatically when the
script is run. So I'd guess it isn't null. Probably the
getComponentForObject("meiosisView") is returning null. The context is
this class:
org.concord.otrunk.script.ui.OTScriptObjectContext
the getComponentForObject is essentially looking up an object in the
referenceObjects list. So it is getting null because the OTModelerPage
isn't in that list.
