IBM BPM/BAW - Coach View Life Cycle

[@bernan6942]

Hi, Thank you for the videos. I have a question about using the Stack component in a view. With this component you can switch between tabs of a table. I have a button on the view with this code :
Var stack1 = this.ui.get("ClStack1");
stack1.setCurrentPane(1);
When i click this button the brwoser gives me this error:
Cannot read properties of undefined (reading 'setCurrentPane')
I dont know what to do to get this stack component to work. Can you help me?
