Using the attached module, There's an asymmetry between fget and fset in
my properties. fget works fine, but fset isn't getting called. I'm
fairly sure I'm creating the property correctly. Try the following code:
a = EWAssayIntParam('myparam', 4)
a.value
a.value = 10
a.value
I've seen this same issue flare up and die out several times in the
tracker, is this a commonly made programming mistake rather than a bug?

This is caused by EWAssayParam being an old-style class. Dunno if it is a bug in Python or not. |

It's not a bug in Python. Properties, being descriptors, only work fully with new-style classes. |
