Grails populating a domain instance

I am wanting to pass a childInstance object from my view to the controller at the moment I am doing this

<g:formRemote url="[action: 'updateStatus']" update="messages" name="updateStatusForm" onSuccess="document.updateStatusForm.message.value='';">

the updateStatus method is as follows

def updateStatus(String message) {
        def status = new Post(message: params.message, author: lookupPerson())
        System.out.println("status: " + status.message + " : " + status.author)
        status.save(flush: true, failOnError: true)
        def messages = currentUserTimeline()
        render template: 'profileMessages', collection: messages, var: 'profileMessage'
    }

I want to add a childInstance from my view to the updateStatus. But I also want to to work if I don’t pass the childInstance to the update Status.

I hope this makes sense.

Add this to the url

url="[action: 'updateStatus' params:[id:'obj.id']]"

and call it in your controller method with

object = Obj.get(params.id)
