I have a simple paginate issue and get the following error...
Hoping for some advice. I am relearning grails using version 2.1 and when I attempt to make a page with the paginate section is it failing.

Here is the controller and i set the default page to activeEvents :
package tictoc
import tictoc.Event
class StoreController {
Event event
static defaultAction = "activeEvents"
def activeEvents = {
log.error 'exec activeEvents'
def max = Math.min(params.max?.toInteger() ?:10, 100)
def offset = params.offset?.toInteger() ?: 0
def total = Event.countByActive(true)
def eventList = Event.withCritera {
eq 'active', params.active
projections {
event {
order 'name'
}
}
maxResults max
firstResult offset
}
return [events:eventList,
totalEvents:total,
active:params.active]
}
}
