Hey, We're trying to interface to a testing instrument (agilent VSA) that has a factory function returning an abstract class, which implements some remoting interfaces (MarshalByRef, etc...)
The instance is returned, but trying to call any method on it (including __str__/__repr__) results in this error message: Traceback (most recent call last): File "<string>", line 1, in <module> SystemError: Type 'System.Runtime.CompilerServices.CallSite`1[[System.Func`4[[System.Runtime.CompilerServices.CallSite, System.Core, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089],[System.Object, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089],[IronPython.Runtime.CodeContext, IronPython, Version=2.7.0.40, Culture=neutral, PublicKeyToken=7f709c5b713576e1],[System.Object, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]], mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]]' in Assembly 'System.Core, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' is not marked as serializable. What can I do to further analyze this problem? Regards, Avi
