[Pythonmac-SIG] aeve and Safari

[John Weeks]

Trying to see how aeve handles the scripting of Safari and compare
it to AppScripting, I am having problems figuring out how to call 
"do JavaScript" using aeve as well.

I have a little program that works fine:

    import aeve
    saf = aeve.talkto('com.apple.safari')
    from aeve.Applications import Safari
    newdoc = saf.make(new=Safari.document)
    newdoc.URL = "http://web.lexis-nexis.com/"

Looking at the aeve-generated dictionary for Safari, I tried to 
implement the AppleScript:

    set the load_status to (do JavaScript "document.readyState" in document 1)

as:

    import aeve
    saf = aeve.talkto('com.apple.safari')
    from aeve.Applications import Safari
    newdoc = saf.make(new=Safari.document)
    newdoc.URL = "http://web.lexis-nexis.com/"
    load_status = newdoc.do_JavaScript("document.readyState")

But I get the following error:

  File "test2.py", line 5, in ?
    newdoc.URL = "http://web.lexis-nexis.com/"
  File "/System/Library/Frameworks/Python.framework/Versions/2.3/lib/python2.3/site-packages/aeve/aetypes/aecomplex.py", line 246, in __set__
    ObjectSpecifier.__set__(self, frominstance, tovalue)
  File "/System/Library/Frameworks/Python.framework/Versions/2.3/lib/python2.3/site-packages/aeve/aetypes/aecomplex.py", line 127, in __set__
    _from_instance=frominstance,
  File "/System/Library/Frameworks/Python.framework/Versions/2.3/lib/python2.3/site-packages/aeve/aetypes/aecomplex.py", line 468, in bound_event_method
    return self(inst, *args, **kwargs)
  File "/System/Library/Frameworks/Python.framework/Versions/2.3/lib/python2.3/site-packages/aeve/aetypes/aecomplex.py", line 493, in __call__
    raise aetools.Error, aetools.decodeerror(_reply, _arguments, _attributes)
aeve.aetypes.aetools.Error: (1, u'NSReceiverEvaluationScriptError: 4', None)

I also tried:

    import aeve
    saf = aeve.talkto('com.apple.safari')
    from aeve.Applications import Safari
    newdoc = saf.make(new=Safari.document)
    newdoc.URL = "http://web.lexis-nexis.com/"
    load_status = saf.do_JavaScript(in_=newdoc,_object='document.readyState')
    
But I get the same error.

Thanks for any help,
