B4J Question [ABMaterial] Auto-Update Connected Browsers

[rwblinn]

A cross check if below is the right appraoch to auto-update all connected browers to an ABMaterial application.
The solution is based on this thread. Have tested and is working fine.

Question: Is this also the right approach using ABMaterial?

Project.b4j

Public ConnectedBrowsers As Map
...
ConnectedBrowsers = srvr.CreateThreadSafeMap
ProjectShared.Initialize

   DataCollectionTimer.Initialize("DataCollectionTimer", 5000)
   DataCollectionTimer.Enabled = True
...
End Sub

Sub DataCollectionTimer_Tick
   For Each clt As ABMPageTest In Main.ConnectedBrowsers.Keys
     CallSubDelayed3(clt, "updatepage", Value,DateTime.Time(DateTime.Now))
   Next
End Sub

Module Class ABMPageTest

Private Sub WebSocket_Connected (WebSocket1 As WebSocket)
