How to close rosgscreen using onkeyevent() in scene graph xml ?

I have created ConfirmSignout.xml scene in. main.brs to show some dialog pop-up with two buttons. If I call dismissSignoutdialog() in onKeyevent, pop-up and rosgscreen has to close and focus will be on the previous screen. But for me if I call dismissSignoutdialog(), rosgscreen is not getting closed.[/font]
Main.brs.[/font][/color]
sub ConfirmSignOUT() As Object
    screen = CreateObject("roSGScreen")
    m.port = CreateObject("roMessagePort")
    screen.setMessagePort(m.port)
    scene = screen.CreateScene("ConfirmSignout")
    screen.show()
    while(true)
        msg = wait(0, m.port)
        msgType = type(msg)
        if msgType = "roSGScreenEvent"
          if msg.isScreenClosed() then 
            return -1
            exit while
          end if 
        end if
    end while
End sub

ConfirmSignout.xml
<component name = "ConfirmSignout" extends = "Scene" >
  <script type = "text/brightscript" >
    <![CDATA[
     sub init()
        m.top.backgroundURI ="pkg:/images/rsgde_bg_hd.jpg"
        dialog = createObject("roSGNode", "Dialog")
        'dialog.backgroundUri = "pkg:/images/rsgde_dlg_bg_hd.9.png"
        dialog.optionsDialog = false
        dialog.title = "Alert"
        dialog.message = "Are you sure you want to Signout?"
        dialog.buttons=["No","Yes"]
        dialog.visible = true
        m.top.dialog = dialog
    end sub

    sub dismissSignoutdialog()
        m.top.dialog.close = true
    end sub

    function onKeyEvent(key as String, press as Boolean) as Boolean
        button_val = m.top.dialog.buttonSelected
        if not press then
            if key = "OK"
                if(button_val = 0)
                    dismissSignoutdialog()
                    return true
                else if (button_val = 1)    
                    print "m.top";m.top
                    'return true
                end if  
            end if

    Are you trying to close the whole Scene Graph application and exit back to the Home screen, or close something else and keep the application running?

            if(scene.visible = false)
              screen.Close()
              return Invalid
            endif
        end while    
    End sub

    ConfirmSignout.xml

    Follow the Code below
    Main.brs
     screen = CreateObject("roSGScreen")
      m.port = CreateObject("roMessagePort")
      m.global =screen.getGlobalNode()
      m.global.id="GlobalNode"
      m.global.addFields({tempmessage:"Are you sure you want to Signout?"})
      screen.setMessagePort(m.port)
      scene = screen.CreateScene("ConfirmSignout")
      screen.show()


    ConfirmSignout.xml

    sub init()
      print m.global.tempmessage
      m.top.backgroundURI ="pkg:/images/rsgde_bg_hd.jpg"
      dialog = createObject("roSGNode", "Dialog")
      dialog.optionsDialog = false
      dialog.title = "Alert"
      dialog.message = m.global.tempmessage
      dialog.buttons=["No","Yes"]
      dialog.visible = true
       m.top.dialog = dialog
    end sub


    You can see the tempmessage. Now you can use it in your dialog
    Note: You cannot go back to main.brs once you create the scene

    Hi Anish,

    Yes, i have a solution,

    Main.brs

        screen = CreateObject("roSGScreen")
        m.port = CreateObject("roMessagePort")
        screen.setMessagePort(m.port)
        scene = screen.CreateScene("exitpopup")
        screen.show()
        scene.setField("tempmessage","Are you sure you want to exit YuppTV?")

    xml code

    <interface>
          <field id = "tempmessage" type = "String"  />
    </interface>
       
      <script type = "text/brightscript" >
     
        <![CDATA[
     
        sub init()
    m.top.backgroundURI = "pkg:/images/rsgde_bg_hd.jpg"
    m.top.bak_press = "0"
    m.top.blocker = 0
    m.top.ObserveField("tempmessage", "Exitpopupdialog")
        end sub
     
        sub Exitpopupdialog()
    dialog = createObject("roSGNode", "Dialog")
    'dialog.backgroundUri = "pkg:/images/rsgde_dlg_bg_hd.9.png"
    dialog.optionsDialog = false
    dialog.title = "Exit Application"
    dialog.message = m.top.tempmessage
    dialog.buttongroup.buttons =["Continue watching","Exit app"]
    dialog.focusButton = 0
    dialog.visible = true
    m.top.dialog = dialog
    m.top.setFocus(true)
    m.top.dialog.ObserveField("buttonSelected","ButtonPressed")
    end sub


    try this it will work for sure
