I had this same problem (needing to specify the "insertion location")  
when I was doing a lot of application scripting with gensuitemodule. I  
wrote a few helper functions which Jack put in aetools which make it  
convenient to specify a relative insertion location. Read on...

I tried this with TextEdit, and had the same problem. I couldn't make a  
new document without specifying the insertion location:

 >>> import aeve
 >>> te = aeve.talkto('TextEdit.app')
 >>> from aeve.Applications import TextEdit
 >>> te.make(new=TextEdit.document)
Traceback (most recent call last):
   File "<stdin>", line 1, in ?
   File  
"/Library/Frameworks/Python.framework/Versions/2.3/lib/python2.3/site- 
packages/aeve/aetypes/aecomplex.py", line 467, in bound_event_method
     return self(inst, *args, **kwargs)
   File  
"/Library/Frameworks/Python.framework/Versions/2.3/lib/python2.3/site- 
packages/aeve/aetypes/aecomplex.py", line 489, in __call__
     raise aetools.Error, aetools.decodeerror(_reply, _arguments,  
_attributes)
aeve.aetypes.aetools.Error: (8, u'NSInternalScriptError', None)

So, on a hunch, I tried my helper function and it worked fine. This  
should also work for you in your attempt to get OmniGraffle to do your  
bidding:

 >>> import aetools
 >>> e = aetools.end(None)
 >>> te.make(new=TextEdit.document, at=e)

Note that in this case, we want to insert the document at the end of  
the application, so we pass None (no target means "the application"),  
in your case you'll probably have to pass the document you want to make  
the shape in:

 >>> aetools.end(te.document[0])
InsertionLoc(document(1), Enum('end '))


Bob, you can look at the source of the aetools.end function yourself,  
it just builds a specifier with the right enumeration code ('end ')

There isn't really any. Personally, I'm glad you are bringing up these  
questions (keep it up! :-). There are lots of people working on a lot  
of not-really-finished ways to script applications using AppleEvents  
with Python, but we're all doing it in our spare time, so none of the  
techniques are really fully finished or well documented yet. Everyone  
has different use cases for wanting a bridge, and some people will do  
things that nobody has ever tried to do before. As we find out what the  
rough spots are, we can polish them off and hopefully converge towards  
a mechanism for scripting applications that is both highly pythonic and  
highly compatible (and easy to use)
