webflow in grails application

Question

how can i redirect to the same state more than one time using web flow ex:

on('submit'){
    def destinationInstance = Destination.get(params.destination)
    def destinationGroupsInstance = DestinationGroup.get(params.destinationGroups)
    def h = destinationInstance.addToDestinationGroups(destinationGroupsInstance)
}.to('flowList')

what i need is how to enter to this state more than one time until destinations ends thx

Well, you'd probably have something like the following code, which is untested but may give you a general idea.

def destinationFlow = {

    initialize {
        action {
            flow.destination = Destination.get(params.id)
        }
        on('success').to 'destinationList'
    }

    destinationList {
        render(view: 'destinationList')
        on('addDestination') {
            def destinationGroup = DestinationGroup.get(params.destinationGroupId)
            flow.destination.addToDestinationGroups(destinationGroup)
        }.to 'destinationList'

        on('finish').to 'done'
    }

    done {
        flow.destination.save()
        redirect(...) // out of the flow
    }
}

You'll need buttons on your destinationList view that invoke the 'addDestination' or 'finish' actions. See the WebFlow documentation and Reference Guide.
