Question

Who knows is it possible to know which leaf item in NestedList were tapped and use this value in the Store?
May be I can use leafitemtap not only in listeners of NestedList?

Answer 1

According to this:

http://docs.sencha.com/touch/2-0/#!/api/Ext.dataview.NestedList-event-leafitemtap

the leafitemtap listener function gives you the following params:

leafitemtap( Ext.dataview.NestedList this, Ext.List list, Number index, Ext.dom.Element target, Ext.data.Record record, Ext.event.Event e, Object eOpts )

in which:

• this points to your current nested list
• index is the index of tapped item
• target is the DOM element of tapped item
• record is the model object of tapped item

Suppose that your model has an id field. Then:

record.get('id') will return the id of tapped item. You can use this to look it up later in your Store.
