Argument type with FileManager.MakeDirectory

Hi,

I have a issue with this function, it seems there is a problem while parsing argument.
I have the following code :

  ..         
  print type(datacenter)
  file_manager.MakeDirectory("[datastore1]/myvm/", datacenter)
  ...

Here the error and ouput :

<class 'pyVmomi.VmomiSupport.vim.Datacenter'>

File "myapp/vmware/vim.py", line 109, in manage_volumes
    file_manager.MakeDirectory("[datastore1]/myvm/", datacenter)
  File "/myapp/.venv/fabenv/lib/python2.7/site-packages/pyVmomi/VmomiSupport.py", line 560, in __call__
    return self.f(*args, **kwargs)
  File "/myapp/.venv/fabenv/lib/python2.7/site-packages/pyVmomi/VmomiSupport.py", line 374, in _InvokeMethod
    map(CheckField, info.params, args)
  File "/myapp/.venv/fabenv/lib/python2.7/site-packages/pyVmomi/VmomiSupport.py", line 949, in CheckField
    % (info.name, info.type.__name__, valType.__name__))
TypeError: For "name" expected type str, but got vim.Datacenter

Fatal error: One or more hosts failed while executing task 'process_run_vmware_item'

Underlying exception:
    For "name" expected type str, but got vim.Datacenter

Aborting.

Do you have any ideas ?

Start by checking the MakeDirectory invocation and the argument validation path shown in pyVmomi/VmomiSupport.py, especially _InvokeMethod and CheckField. Confirm the declared parameter order and reproduce the reported TypeError with the supplied call. Done should be a documented or tested resolution that clearly distinguishes the accepted argument types.
