Here's a session example that I'm running in ipython now:
>>> b = vcs.createboxfill()
>>> b
<vcs.boxfill.Gfb at 0x1021f5ec0>
>>> b.name
'__boxfill_419032409050676'
>>> b.rename("test")
>>> vcs.elements['boxfill']['test']
<vcs.boxfill.Gfb at 0x1021f5ec0>
>>> vcs.show('boxfill')
*******************Boxfill Names List**********************
a_boxfill a_lambert_boxfill a_mollweide_boxfill
a_polar_boxfill a_robinson_boxfill default
polar quick robinson
test
*******************End Boxfill Names List**********************
>>> new_b = vcs.getboxfill('test')
>>> new_b
<vcs.boxfill.Gfb at 0x1021f5ec0>
>>> new_b.name
'__boxfill_419032409050676'
# assume we have a cdms2 variable named 's', and a Canvas named 'a'
>>> a.boxfill(s,b)
vcsError: Error source boxfill object (__boxfill_419032409050676) does not exist!As we can see from the example, this leaves behind a reference to the renamed boxfill in the names list while making that boxfill unusable, because it is deleted.
I think the issue is that we should just be creating a new boxfill here, instead of using vcs.elements to re-assign things:
Not sure if this is a widespread problem (affecting more than just Gfb).
