SAP FIORI OVP tutorial with cds : numbers not displayed.

Hello all (gurus and others)...

I have followed the excellent blog from Jamie Cawley at :http://scn.sap.com/community/developer-center/front-end/blog/2016/07/05/creating-a-fiori-ovp-application-with-cds-view-annotations--part-1

everything is working perfectly, except that when i run the app I do not get the numbers displayed :

My CDS View is defined as :

@AbapCatalog.sqlViewName: 'zovpdemo1'

@AbapCatalog.compiler.compareFilter: true

@AccessControl.authorizationCheck: #CHECK

@EndUserText.label: 'OVP Demo App on Gateway'

@OData.publish: true

define view Z_Ovp_Demo1 as select from sepm_cds_sales_order as so {

key so.sales_order_key,

@UI.selectionField: [{ position: 10 }]

@UI.lineItem: { position: 10, qualifier:'ordOverView', label: 'Sales Order' }

so.sales_order_id,

so.created_by,

so.created_at,

so.changed_by,

so.changed_at,

so.note_guid,

so.currency_code,

so.gross_amount,

@UI.lineItem: { position: 30, qualifier:'ordOverView', label: 'Net Amount'}

so.net_amount,

so.tax_amount,

so.lifecycle_status,

so.billing_status,

so.delivery_status,

so.buyer_guid,

/* Associations */

so.customer,

so.items,

@UI.selectionField: [ { position: 20 } ]

@UI.lineItem: { position: 20, qualifier:'ordOverView', label: 'Customer' }

so.customer.company_name

}

Could someone help to figure out where is the error/bugs ?

Thanks.
