As per the mailing list post in the specified URL, -[WebScriptObject callWebScriptMethod:withArguments:] translates an exception raised in the called method into a return value of WebUndefined. This makes it impossible to distinguish between a genuine return value of undefined and an exception being thrown. -[WebScriptObject callWebScriptMethod:withArguments:] returns nil in other situations: if the given method doesn't exist on the object, or if it is not a callable. It may make more sense to handle exceptions in a similar way, though the compatibility impact of changing the return value in this case is unknown.
