There is no sort indicator displayed on any column on initial show. Setting piOrdering does not work, however setting piSortColumn to 0 works (sort indicator displayed and search works). Simplified code below incase I am doing something obviously wrong.

Code:
// C:\VDF_Area_18\vdfws\covecommon\AppSrc\WebActionsManagement.wo
// Actions Management
//
Use cWebModalDialog
Use cWebPanel.pkg
Use cCoveWebButton.pkg
Use cWebPromptList.pkg
Use cWebColumn.pkg
Use cWebColumnLink.pkg
Use cWebColumnButton.pkg
Use WebActionsDetail.wo
Use actions.DD

Object oWebActionsManagement is a cCoveWebView
  Set piColumnCount to 12
  Set psCaption to "Actions Management"
  //Set piWidth to 700
  Set piHeight to 400

  End_Object 
  Set Main_DD to Actions_DD
  Set Server  to Actions_DD

    Object oGrid is a cWebList
      Set pbFillHeight to True

      Set piOrdering to 2       // Do not work
      //Set piSortColumn to 0       // Works
      
      Object oActionsACTION_NO is a cWebColumn  
        Entry_Item Actions.ACTION_NO

    Object oOkButton is a cCoveWebButton
