Nativescript 2.2 exception

问题

Getting the following exception with 2.2.

Was working with previous version.

Did "tns info" and all is updated to 2.2

I tested this scenario with latest tns-core-modules and nativescript-angular and everything works as expected. As @Panayot.Cankov suggested you should upgrade to tns-core-modules@2.2.0 and nativescript-angular@0.3.0. You could do that using following commands:

tns plugin remove tns-core-modules
tns plugin add tns-core-modules@2.2.0
tns plugin remove nativescript-angular
tns plugin add nativescript-angular@0.3.0

Upgrade both the tns-core-modules@2.2.0 and nativescript-angular@0.3.0. After some refactoring we introduced the cssClasses Set on the View classes in the tns-core-modules but by unhappy coincidence the nativescript-angular was extending by monkey-patching its own cssClasses Array property on the View class. It has been resolved, but new versions of the tns-core-modules will not be compatible with old versions of the nativescript-angular.

Make sure you upgrade your angular dependencies too, i was receiving the same error until i bumped to rc4. the below dependencies work for me now.

"@angular/common": "2.0.0-rc.4",
    "@angular/compiler": "2.0.0-rc.4",
    "@angular/core": "2.0.0-rc.4",
    "@angular/http": "2.0.0-rc.4",
    "@angular/platform-browser": "2.0.0-rc.4",
    "@angular/platform-browser-dynamic": "2.0.0-rc.4",
    "@angular/platform-server": "2.0.0-rc.4",
    "@angular/router-deprecated": "2.0.0-rc.2",
    "nativescript-angular": "^0.3.0",
    "nativescript-drop-down": "^1.3.2",
    "rxjs": "5.0.0-beta.6",
    "tns-core-modules": "^2.2.1",
    "zone.js": "^0.6.12"
