"choices" in datasheets not handled correctly

[wagn0033]

If a field in the datasheet has a list of choices, then when trying to add or edit an item, you get a drop-down list where you select one of those choices. However, it seems to only work correctly if that list contains a boolean or a string. If I add None, an integer, or a dictionary to that list, they all show up as possible choices, but when I try to save it, even though it appears to be updated, if you fetch that record in a different window or via the REST API, it is still whatever the value was before.

I haven't tried the equivalent with tests yet.
