Almost everything is in the title 😉

When you create a TreePanel you can add a loader this way:

loader: new Ext.tree.TreeLoader({
  dataUrl: '../myurl.php'
});

But how to handle load errors?

For example if the user is not connected I want to display a Login box.

I can’t find an example showing how to handle loading errors with TreeLoader and/or TreePanel.
