You just need to define the model in the onit of the component.js as

var myModel = new JSONModel();

myModel.loadData("filepath.json");

this.setModel(myModel,"invoice");

Hi,

If the model has data then do as suggested by Jun i.e. add the shown line in index.html file where you are loading the SAPUI5 core.

[junwu]

your model name is Invoices

items="{Invoices>/Invoices}"

[jamie_cawley]

Correct your model alias in the component.js

this.setModel(myModel,"invoice");
