I am using ExtJs 4.2. Am using property useArrows:true in my tree panel. How to show the collapse/expand icon on a node without children in a tree panel.On expand and collapse it should fire all the events related to the tree panel.

I tried adding

1-children:[{}] gave me undefined property.

2-loaded:true nothing happened

3-singleExpand:true nothing happened

4-allowChildren:true nothing happened

One hack is to actually add children items to the node but hide them with css. So you would do something like:

#tree_element_id .x-grid-tree-node-leaf{
  display:none;
}
