Need another pair of eyes... f:param not set in request
The value for param (selection) is not being set in the request map for a panelMenuItem.
No matter what menu item I select the request map returns null for the param named: selection. What am I doing wrong?
I need another pair of eyes to look at this code:

Code to look for Param named: selection. The result is always null. Why?
public void updateSelection() {
FacesContext facesContext = FacesContext.getCurrentInstance();
Map params = facesContext.getExternalContext().getRequestParameterMap();
String selection = (String) params.get("selection");
if (selection != null) {
menuState.setSelectedMenuItem(MenuConstants.LDPFeatureFlightDispatch, selection);
}
}
Note: when mode is "ajax" the param IS set but my page is not re-rendered. Help!
