How to make reusable component

Hello,



I started to use Sencha Architect to make an application. I want to make a reusable composant that extends the

Code:

---

ComboBox

---

composant and add some checkbox in it. Then i want to make it available in the toolbar.

In fact the composant already exist: Ext.ux.form.LovCombo



I tryed to follow the documentation to create user extensions but didn't succeded. The documentation about the package.json isn't up to date?



And many other post like this one.



It's been a day that i try to do this simple task but without succeeding. I begin to think that Sencha Architect is not as good as it seems to build an industrial application...
