== What Happened to !ViewState? ==

In Model-Glue 3, the viewstate was deprecated. As of Model-Glue 3, the proper way to get values while you are in a view is through the Event object.
 
You may get a single parameter by using:

{{{
<cfset foo = event.getValue("foo") />
}}}

You may get multiple parameters in a single statement by using:

{{{
<cfset event.copyToScope(variables, "foo,bar,baz") />
}}}
