I'm not an expert in this, but I think the maybe-resolve functions
only do lookups when the spec is a string, and pass non-strings
through unchanged. As far as I know lambdas are regular functions, so
I'd expect it to pass them through like view callable functions. Maybe
another exception is occurring, and when Python tries to print the
traceback, it can't find the lambda's source.
I generally use regular functions instead of lambdas, but I realize
this is a stylistic choice and some think otherwise. A partial might
work in your use case:
config.add_view( functools.partial(_delete_multi,
arg2_keyword=Doc2Resource) , ...
