import {Component,View,Input} from 'angular2/core';
import {
    RouteConfig,Router,RouteParams,ROUTER_DIRECTIVES
} from 'angular2/router';
import {PersistentRouterOutlet} from './persistent-router-outlet';


@Component({})
@View({
  template: 'product info here'
})
class ProductInfo {
}

@Component({})
@View({
  template: 'buy here'
})
class ProductBuy {
}


@Component({})
@View({
  directives: [...ROUTER_DIRECTIVES,PersistentRouterOutlet],template: `
    <div>
      <h2>Product {{pid}}</h2>
      <a [routerLink]="['Info']">Show Info</a>

})
@RouteConfig([

  pid
  constructor(params: RouteParams) {
    this.pid = params.get('pid')
  }
}

@Component({})
@View({

class StoreInfo {
}


@Component({
