NestedList - jump to a card ( setActiveItem ? )

[NJS]

Hello

I am trying to trigger a nestedlist to open a specific detailcard.

I'm trying to use the setActiveItem method but am unsure of the syntax, so...
- how do I target the nestedlist? (can I use Ext.getCmp) ?
- how do I target the detailcard to open?

I've tried:

var myNestedList = Ext.getCmp('nestedListComponentID');
myNestedList.setActiveItem(3); // set by component ID and card index?
myNestedList.setActiveItem('detailcardxtype'); // set by detail card's xtype name as set in the store?
myapp.views.NestedListMenu.setActiveItem(3); // from where the list was created, eg myapp.views.NestedListMenu = Ext.extend(Ext.NestedList, {...

plus so many more combinations, just can't nail it. Please put me out of my misery

PS. I also set the layout of the nestedlist to

layout: {type: 'card'}

Any help would be most appreciated!
Thanks

NestedList already uses card layout so you do not need to set it. To target the NestedList I would not use id and getCmp. You can put it on the namespace or use ComponentQuery to resolve it. NestedList switches active item per the node that was tapped.

Can you jump to a NestedList detailCard programmatically, using setActiveItem?
