`WallType.Name` returns error

[GoogleCodeExporter]

What steps will reproduce the problem?

in the shell...I wanted to get the wall types "Name" but came up with an error
even there is a property, by dir()-ing it.

>>>wallTypes=list(doc.WallTypes)

>>>wallType=wallTypes[0]

>>>wallType.Name

IronTextBoxControl error: Name
>>>dir(wallType)

What is the expected output? What do you see instead?

What version of the product are you using? On what operating system?
Revit2012 / latest revitpythonshell

Please provide any additional information below.
seems that properties inherited from ElementType gives an error?

I can reproduce this. I am looking into it right now.

The following session in the interactive shell displays a hint at the problem:

    >>> wallTypes = list(doc.WallTypes)
    >>> wt = wallTypes[0]
    >>> wt.Name
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
    AttributeError: Name
    >>> wt.get_Name
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>   
    AttributeError: 'WallType' object has no attribute 'get_Name'

    >>> wt.GetType().GetProperty('Name').GetGetMethod().Name
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
    AttributeError: 'NoneType' object has no attribute 'Name'
    >>> wt.GetType().GetProperty('Name').GetSetMethod().Name
    'set_Name' 
    >>> 

It seems, there is no "getter" for the `Name` property. This is strange!

According to the RevitAPI 2012, this is correct behavior:

    public override string Name { set; }
    # (inherited from `ElementType`)
    # Set the name for the ElementType.
    # This method will assign the element type a new name.

Thus, `ElementType` overrides the `Element.Name` property. You can still access 
it like this:

    >>> wallTypes = list(doc.WallTypes)
    >>> wt = wallTypes[0]
    >>> Element.Name.__get__(wt)
    'STB 30.0'
    >>> 

This tells IronPython to use the *getter* of the `Name` property of the 
`Element` type on the object `wt`. It *is* a bit cumbersome, but not really a 
bug (at least not in RPS, it might be considered a bug in IronPython, but I 
think it is OK)!
