appstruct values of None render as "None"

[ghost]

Would it be better to render values as "" when given an appstruct value of None, as opposed to "None"?

appstruct={
    'some_value': None,
}

<input value=""

as opposed to:

<input value="None"

This has to do with colander. For some types it blindly translates the values it's given into a string value (str(None) == "None"). You need to change your code to either give an empty string or a colander.null in the appstruct.
