Issue Overview

Multi-level menu fail to auto activate when nested on level > 1

Current Behaviour

Left bar menus are activated (open) on page enter up-to neste level 1. On nest level > 1 the auto open functionality wasn't working.

Expected Behaviour

All levels are open.

How to reproduce

Create a multi-level menu as demonstrated on "AdminLTE" (https://adminlte.io/themes/AdminLTE/index2.html)
They fail to maintain open stickness on page reload.

Additional Information

• AdminFaces version: RC19
• PrimeFaces version: should be irrelevant
• JSF implementation: should be irrelevant
