$q

synchronize async dependencies

Problem

Initialize i18n strings for multiple dependencies.

SystemSrv gets i18n strings from server and sets the page title after getting response

OrderCtrl should not be initialized before strings are loaded.

Sync to seam/resource/api/system is needed in two or more places.

Solution

$q promises

SystemSrv.deferred = $q.defer()

SystemSrv.deferred.promise = SystemSrv.deferred.promise.then ->

init code

pass in SystemSrv where sync is needed.

Questions?

Example

 deferredFirstService = $q.defer()
  deferredFirstService.promise.then ->
    $scope.OrderCtrl.init()
  
  
  SystemSrv.deferredSystem.promise = SystemSrv.deferredSystem.promise.then( ->
    $scope.OrderCtrl.catalog = $scope.OrderCtrl.catalog.get({offeringId: sscUtils.getQueryParam('id')}, 
      () -> 
        deferredFirstService.resolve()
      , 
      (error) -> 
        window.location = 'home.seam'
    )
  )
