Regression: some failures result in a blank form

[abstratt]

In this case, this is the result of creating a new cart for the current customer. The URL looks like this:

http://localhost/kirra-angular/?theme=&app-uri=http://localhost/services/api-v2/demo-cloudfier-apps-cesta/#/cesta.Cesta//show

Note the lack of an objectId for the cart.
