Aaron,
If you are after a reference to the LoginController, you could try this:
VariableResolver vr =
FacesContext.getCurrentInstance().getApplication().getVariableResolver();
LoginController lc =
(LoginController)vr.resolveVariable(FacesContext.getCurrentInstance(),
"LoginCtl");
This is simpler than creating a value binding. It will use the whole
managed bean deal to create the bean if it doesn't exist, etc.
