How to display the error messages from the controller
I have a wizard which consists of two pages. To keep it simple let''s say
that the first page asks the user to select a state from the drop down menu.
In case the user doesn''t select any state, an error message needs to be
displayed.
Ideally I would like to do something like this.
def new
selected_value = params[:addevent][:state_id]
if selected_value == "-1"
