cdms.createAxis errors with cdms.createVariable object as input

[durack1]

I have just encountered a new problem with the cdms2.createAxis function as captured below:

If I use a non-cdms transient variable as an input, this works fine:

In [10]: import cdms2 as cdm
In [11]: cdm.createAxis([10.],id='height')
Out[11]: 
   id: height
   Length: 1
   First:  10.0
   Last:   10.0
   Python id:  0x7f0b601f3650

However, if I try using a cdms transient variable as the input, I get the following error. This is new in cdms2-2.12-np113py27_0 which was installed as part of the cmor331 release:

In [12]: cdm.createAxis(cdm.createVariable([10.],id='height',missing=1e20))

    result.append('   Length: ' + str(len(d)))
TypeError: object of type 'float' has no len()

The issue appears to occur in all releases dating back to 2.8.0 (so also 2.10 and 2.12)

Inconceivable!

@dnadeau4 agreed, I too was flabbergasted at this discovery..

@durack1 my changed made everything failed on OSX, but passed on Linux. I have to revert.

[durack1]

@dnadeau4 weird, I wonder why the difference on platforms

This is still an issue on OSX CDAT 8.1/CDMS2 3.1.2:
