Question

I have 6 columns in my domain class. But i only see 5 columns on the controller list when scaffold is set to true.
My database is mySql. When executed table is created with correct number of columns
My domain class

class RouteDesc {
String routenumber
String routeoperator
String routeinstructions
Date validfrom
Date validto
String weekendavailablity

static constraints = {
    routenumber blank:false, unique:true,  display:true
    routeoperator blank:false,  display:true
    routeinstructions blank:true,  display:true
    validfrom display:true
    validto display:true
    weekendavailablity display:true
}
//static belongs to = RouteId

String toString () {
    return routenumber
}
}

My Controller class

class RouteDescController {

  static scaffold = true
}

One more addition to what Jarred Olson suggested

props.eachWithIndex { p, i ->
  if (i < 6) {
   ...
  }

}

Also change

<td><g:link action="show" id="\${${propertyName}.id}">\${fieldValue(bean: ${propertyName}, field: "${p.name}")}</g:link></td>
                    <%      } else if (i < 6) {
                                if (p.type == Boolean.class || p.type == boolean.class) { %>
                        <td><g:formatBoolean boolean="\${${propertyName}.${p.name}}" />
</td>
