Coach View - Display error message at Table's Component row level

Display error message at Table's Component row level -

To achieve :
  

Validation Code : (Text Box)

for(var iCount=0; iCount<tw.local.testBO.listLength-1; iCount++){

      if(tw.local.testBO[iCount].userName == null || tw.local.testBO[iCount].userName == "" ){

         var componentName = "tw.local.testBO[" + iCount + "].userName";
         tw.system.addCoachValidationError(tw.system.coachValidation, componentName, "Please provide user details...");
    }                                                   
}    


Validation Code : (Combo Box)

For combo box, it could not be achieved with binding because binding is having list.  It can be done through selected item.

Configuration -- Selected Item -- Assign a Name Value Pair variable. Suppose variable name is "userNameNV".

for(var iCount=0; iCount<tw.local.testBO.listLength-1; iCount++){

      if(tw.local.testBO[iCount].userNameNV == null ||
                                tw.local.testBO[iCount].userNameNV == "" ){

         var componentName = "tw.local.testBO[" + iCount + "].userNameNV";
         tw.system.addCoachValidationError(tw.system.coachValidation,
                                                                  componentName, "Please provide user details...");
    }                                                   
}
