Close BusySpinner After Data Load

Archived

Using the busyspinner example in the sdk but having some difficulty in getting it right. When channel starts the busyspinner comes up and runs but never goes away to allow contents to show. I have something like the following. I know this might be simple fix but not able to figure it out. How do I make the spinner go away once the serverListdata is done? Thanks


	Function serverListdata() as object
		showChannelSGScreen() 
               server0="xxxxx"
	       server1="xxxxx"
               server2="xxxxx"
		m.serverList[0]= server0
		m.serverList[1]= server1
		m.serverList[2]= server2
?"SERVER INDEX IS >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>"index
m.serverList=m.serverList[index]
end function

			sub showChannelSGScreen()
  				screen = CreateObject("roSGScreen")
			       m.port = CreateObject("roMessagePort")
			     screen.setMessagePort(m.port)
                            scene = screen.CreateScene("BusySpinnerExample")
			  screen.show()
					  while(true)
					    msg = wait(0, m.port)
					    msgType = type(msg)
						    if msgType = "roSGScreenEvent"
   						      if msg.isScreenClosed() then return
						    end if
					  end while
		end sub
