Thank you for that work around... now I can start the weekend. :-D
There used to be a mytestRun.Field.SetValue in the dir() listing in Beta3:
>>> dir(mytestRun.Field)
['Equals', 'GetHashCode', 'GetType', 'GetValue', 'Item',
'ReferenceEquals', 'SetValue', 'ToString', '__class__', '__delattr__',
'__delete__', '__doc__', '__get_
_', '__getattribute__', '__getitem__', '__hash__', '__init__',
'__name__', '__new__', '__objclass__', '__reduce__', '__reduce_ex__',
'__repr__', '__setattr__',
'__setitem__', '__str__']
But Field.SetValue disappeared in RC2:
>>> dir(mytestRun.Field)
['ComMethodDesc', 'DispatchObject', 'Equals', 'GetHashCode',
'GetMetaObject', 'GetType', 'Item', 'MemberwiseClone', 'Ref
erenceEquals', 'ToString', '__class__', '__delattr__', '__doc__',
'__eq__', '__getattribute__', '__getitem__', '__hash__
', '__init__', '__ne__', '__new__', '__reduce__', '__reduce_ex__',
'__repr__', '__setattr__', '__str__']
I didn't know what the Dev team had in mind. Some things became more
straightforward but I couldn't get this critical piece to work.
Additional dir() output on RC2:
>>> dir(mytestRun.Field.Item)
['Equals', 'GetHashCode', 'GetType', 'GetValue', 'Item',
'MemberwiseClone', 'ReferenceEquals', 'SetValue', 'ToString', '
__class__', '__delattr__', '__delete__', '__doc__', '__get__',
'__getattribute__', '__getitem__', '__hash__', '__init__'
, '__name__', '__new__', '__objclass__', '__reduce__', '__reduce_ex__',
'__repr__', '__setattr__', '__setitem__', '__str
__']
I already found and tried Item's SetValue but encountered the same
SystemError. I tried to find the expected inputs:
>>> print mytestRun.Field.Item.SetValue.__doc__
bool SetValue(self, CodeContext context,
SiteLocalStorage[CallSite[Func[CallSite, CodeContext, object,
Array[object], ob
ject]]] storage, Array[object] keys, object value)
I may have gotten close, but no cigar:
>>> mytestRun.Field.Item.SetValue(Array[object](["RN_DURATION"]),"10")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
SystemError: Object reference not set to an instance of an object.
The requested 2.0 RC2 output:
>>> dir(mytestRun)
['Attachments', 'AutoPost', 'BPStepParamFactory', 'CancelRun',
'CopyDesignSteps', 'CopyStepsToTest', 'CreateObjRef', 'Eq
uals', 'ExtendedStorage', 'Field', 'GetHashCode', 'GetLifetimeService',
'GetType', 'HasAttachment', 'History', 'ID', 'In
itializeLifetimeService', 'IsLocked', 'LockObject', 'MemberwiseClone',
'Modified', 'Name', 'Params', 'Post', 'ReferenceE
quals', 'Refresh', 'ResolveStepsParameters', 'ResultLocation', 'Status',

This might be broken but the output of dir(mytestRun) might be helpful as well
to make sure (e.g. maybe there'll be some set_Field method or something).
But I suspect you might want to pass the -X:PreferComInteropAssembly command
line option and I think that'll restore the beta 3 behavior for you.

I found that one and tried before. I didn't have any luck:
>>> mytestRun.Field.Item['RN_USER_01'] = 'abc'
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
SystemError: Object reference not set to an instance of an object.
>>> print mytestRun.Field.Item['RN_USER_01']
None
I couldn't decipher the error so I couldn't figure out what I'm doing
wrong.
I suspect the folks on this list can. =)

Does:

Subject: [IronPython] 'DispPropertyGet' error returned from read-write COM
interop property
Hi everyone,
I encounter an error with 2.0 RC2 that didn't occur in the same
IronPython code on 2.0 Beta 3.
I use a factory object from a COM interop assembly that has a read-write
property named "Field". I get a TypeError when I assign a value to this
property (read-write):
>>> mytestRun.Field['RN_USER_01'] = 'abc'
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'DispPropertyGet' object is unsubscriptable
>>> print mytestRun.Field['RN_USER_01']
None
I imported the same COM interop assembly that worked with 2.0 Beta3.
The interop was converted with tlbimp.exe from a COM API .dll. Here's
the 2.0 Beta3 output:
>>> mytestRun.Field['RN_USER_01'] = 'abc'
>>> print mytestRun.Field['RN_USER_01']
abc
My best guess is that IronPython 2.0 RC2 interprets the property as
read-only even though the COM interop assembly defines the property
read-write. The error occurs in IronPython 2.0 RC2 with every COM
interop object with the read-write "Field" property.
I can read the default assigned value but cannot assign anything. Any
ideas? I'm fresh out of them after trying many permutations of the syntax.
Thank you,
