Create new Detail Window from detail Window Tab

Hi, thank you in advance,

I’m a new baby in shopware and I’m trying to create create a new detail window when I click in the detail icon in a list. 

To explain better the situation is as follows:

I’m extending an app in  the backend, (the customers App), so far I created another tab to list the contents of a table associated to the customer ID, in that list I can delete rows but when I click in th e Edit icon call for the right action but wont open the detail window.

Can anyone give me some pointer please. 

Thank you


 If they are under same controller and registered under same subscriber this shoud do it. Ext.create('Shopware.apps.Prepare.view.multiPrepare.Window', { productNumbers: productNumbers }).show();
