i've discovered odd behavior array.from . appears not work callback function directly when mapped on array of array-like objects. i've tested in chrome. here's test code (es6): const fails = () => { const x = { 0: 'help', length: 1 }; const y = [x].map(array.from); // throw error return y; }; const works = () => { const x = { 0: 'help', length: 1 }; const y = [x].map(item => array.from(item)); // work return y; }; console.log(works()); console.log(fails()); https://jsfiddle.net/dox6wnya/ this peculiar behavior. i'm wondering why happens. .map passes three arguments callback ( currentvalue , index , array ), , .from accepts 3 arguments ( arraylike , mapfn , thisarg ). types of arguments don't match and/or produce unexpected results; in particular " 0 not function ", 0 index argument passed mapfn . real compatible argument first one, why it's 1 should pass.

we using spring security's acl annotations allow access web services. @preauthorize , @postauthorize seems extremely useful , favours of use cases having. spel based rules on individual methods et al helping in fine grain security on application , services. for eg:- check owner of returned object below @preauthorize("hasrole('role_admin') , returnobject.owner == authentication.name") public somedto getsomedto(){ ... } this works fine when single object returned. equivalent if list returned? how loop through collection , check individual element properties in collection using spel? in case of collection should use @prefilter , @postfilter annotations. when using @postfilter annotation, spring security iterates through returned collection , removes elements supplied expression false. name filterobject refers current object in collection. can filter before method call, using @prefilter, though less common requirement. see exam
