  1. You = should not use a timed update. You should update the CometActor on state = change on the server (time is not state change)
  2. If you post = a reproducible example, we can help you.

Hey guys,
I have a page, that want to render every 10sec. i use = ActorPing.schedule, which same to the demo in lift website.
However, i found that, when use load page in the first cycle of 10sec, = the page will not be rendered  by comet. And, everything work fine, = after 10sec.

Here is the code:



package code.comet


class hotjobs  extends CometActor {
  private var jobs:List[Jobs] =3D Nil

  def render =3D "#hot" #> <table class=3D"table = table-striped">{jobs.flatMap(jobsExtrator _)}</table>

  def jobsExtrator(j:Jobs):NodeSeq=3D
    <tr>
      = <td>{modifyDate(j.createdAt.toString())}</td>
      <td>{j.title}</td>
      <td>{j.companyName}</td>
      <td>{j.location}</td>
      <td style=3D"text-align: right;"><button = type=3D"button" datatoggle=3D"button" = onClick=3D{JsCmds.RedirectTo("/jobDetail.html?jobid=3D"+j.id)}>=C1=A2=BC=B4=C9=EA=C7=EB</button><= ;/td>
    </tr>

  def modifyDate(s:String):String=3D{
    val b =3D s.split(" ")
    return  b(1)+"-"+b(2)+"-"+b(3)
  }


  ActorPing.schedule(this, Message, 10000L)

  override def lowPriority =3D {
    case Message =3D> {
      reRender()
      jobs =3D Jobs.findJobsinTop
      ActorPing.schedule(this, Message, 10000L)
    }
  }
}
case object Message
