🚀 go-pugleaf

I am trying to automatically expand the child nodes when the user clicks and
expands a parent node.

On treeExpanded event handler, I try to expand the children using expandPath
for each of them. Nothing happens.

Before the parent is expanded, its children's children are not loaded, but
children's isLeaf() methods report false; Thus, in the treeExpanded event
handler, I do load the children's children and they are available to be
displayed.

Has anyone ever tackled with a problem like this? I will appreciate any
ideas, examples, tips. Thank you.
Ali.
