  Hi,
  it is possible to use events around the class AddingNewEventArgs or CancelEventargs ?

  The BindingList.AddingNew event do not work under Powershell v2 :

   #The PSMemberSet class has not a default constructor 
  $listOfParts = new-object System.ComponentModel.BindingList[System.Management.Automation.PSMemberSet]
   
  $listOfParts.AllowNew = $true
  $listOfParts.AllowRemove = $True
  $listOfParts.AllowEdit = $True;
   # Raise ListChanged events when new parts are added.
  $listOfParts.RaiseListChangedEvents = $true
  Register-ObjectEvent $listOfParts AddingNew "AddingNew" -Action {
   Write-Warning "args count"; 
   Write-host $event.SourceArgs.Count
   $EventArgs|select * |write-host 
   $obj=New-object System.Management.Automation.PSMemberSet "Test1"
   #$EventArgs.NewObject=$Obj
   $Event.SourceArgs[1].NewObject=$Obj
  }
  Register-ObjectEvent $listOfParts ListChanged "ListChanged" -Action {
   Write-WarnIng "ListChanged"
   $EventArgs|select * |write-host
   Write-Host $EventArgs.ListChangedType.ToString()
  }
  $Newpart=$listOfParts.Add((New-object System.Management.Automation.PSMemberSet "Test0"))
  $Newpart=$listOfParts.AddNew()
   #exception
  # BindingList.AddNew Method (System.ComponentModel)
  $listOfParts.EndNew($listOfParts.Count)

  Is the event handler limited under PowerShell v2 or a is it a bug ?
