node.js - Bluebird promise.all not respecting result order -

i'm using latest stable bluebird:

"bluebird": "~3.4.0", 

and following code:

promise.all([participantsservice.retrieveactiveparticipantsfromthelocaldb(),     eventservice.retrieveactiveeventsfromthelocaldb(),     heatservice.retrieveactiveheatsfromthelocaldb()]).then(     function (results) {         var namedresults = {participants: results[0], events: results[1], heats: results[2]};         return res.render('runners/runners', namedresults);     }).catch(     function (err) {         winston.error('failed retrieve participants , or event details', err);         return res.send(err);     }); 

i expect namedresults have correct order of elements matching order in array of promises have been made not true! have different order every time.

i assuming because says on bluebird's documentation: http://bluebirdjs.com/docs/api/promise.all.html unless i'm reading wrong...

can help?

thanks

you should able use bluebird's promise.props() this:

promise.props({   participants: participantsservice.retrieveactiveparticipantsfromthelocaldb(),   events: eventservice.retrieveactiveeventsfromthelocaldb(),   heats: heatservice.retrieveactiveheatsfromthelocaldb() }).then(res.render.bind(res, 'runners/runners'))
