[CLOSED] Labels not visible in Ext Node of TreePanel
This is a simple multi-column TreePanel. I eventually want to have tri-state checkboxes appear in the TreePanel's columns 2...n but for now have removed all but the first column to demonstrate that the nodes of column 1 don't display the text property (but qtip shows the same value just fine ). Confirmed via page source that text property of node is set and no obvious css issues. I've gone over the examples. Do I need to use an Ext.Store?

root: {
expanded: true,
text: "DecisionList",
children: [{
leaf: true,
expanded: true,
qtip: "Marketing Decisions",
text: "Marketing Decisions"
},{

expanded: true,
qtip: "Production Decisions",
