Hello,

I'm with a project, which allows the user to move between windows, but when returned to the previous window with a button called category the app shows the following error...

  • Looks like your reference to the array item is null. You should check the value before you try and add it to the window.

Hi juan, you can see that error is due to Message: Uncaught TypeError: Cannot call method 'add' of null

then

Source: this.view.add(this._children[i]);

so check you reference here... i think you are trying to add over a view which is released already.
