Sencha Touch - setactiveitem to top level on nested list - sencha-touch

Question

I have a tabpanel with items of nestedlists. Each nested list goes several levels deep. If I drill down one of the nested list, then i click on a different item in the tabpanel, then click back to it, the nested list is still drilled down, instead of refreshing to the top level of the nested list.
How do I get the nestedlist to display the top level instead of the drilled down level everytime I return to it?
Additional Info
OK, I'm part way there. Here's the code I have now:
var tabBar = new Ext.TabPanel({
fullscreen: true,
id : 'footer',
cardSwitchAnimation:false,
listeners: {
cardswitch: {
fn: function() {
Ext.getCmp('footer').getActiveItem().setActiveItem(0);
}
}
},
tabBar: {
dock: 'bottom'
},
items: [/* some nestedlist components */]
});
So the final problem is that everytime I cardswitch, I see the "drillup/slideback" animation of the nested list sliding back or drilling back to the top level item. How do I get it to just show the top level item without this drill up/slide back animation? I want to preserve the slide forward and drill down animation when the user drills down the nestedlist.

Answer 1

You can try to set the cardSwitchAnimation parameter to false in the setActiveItem method
[UPDATE] Deselect item
Add an event listener for the item tap event on the nested list
nestedList.on("itemtap", function(nestedlist, index, item, e){setTimeout(function(){nestedlist(index);},500);}, this);
[UPDATE] From John
For some reason your code didn't do anything for me. But this one worked:
var nestedList = new Ext.NestedList({
store: store,
listeners: {
itemtap: function(dv, ix, item, e) {
// Clear the selection soon
setTimeout(function(){dv.deselect(ix);},500);
}
}
});

Answer 2

In March 2014, with version 2.3.1, I had the above problem with the Ext.dataview.NestedList object. The suggested approach of using the "deselect" method did not work for me - probably because of the two years that have gone by since the original question.
To resolve problem, I used the following:
nestedList.goToNode( nestedList.getStore().getRoot() );
