View not being updated

[Johnny TwoShoes]

Hi,

The data isn't loaded on startup, here is the complete ViewModel, can anyone see anything obvious please , i've been looking at this issue for hours and cannot fix it????  Is it just two editviews (  eg bind:text="${vehicleodometer}" and bind:text="${vehicleregistration}"):

//ViewModel

package com.example.johnnytwoshoes.myapplicationtestgenerator1.ViewModel;

import android.util.Log;

import android.widget.Toast;

import com.example.johnnytwoshoes.myapplicationtestgenerator1.Model.StartshiftActivityModel;

import com.example.johnnytwoshoes.myapplicationtestgenerator1.View.MainActivity;

import com.example.johnnytwoshoes.myapplicationtestgenerator1.View.StartshiftActivity;

import org.robobinding.annotation.PresentationModel;

import io.realm.Realm;

@PresentationModel

public class StartshiftActivityViewModel {

   

   //Constructor

   public StartshiftActivityViewModel(){

       realm = Realm.getInstance(StartshiftActivity.getContext());

       setStartshiftactivitymodel(realm.where(StartshiftActivityModel.class).findFirst());

       if(startshiftactivitymodel == null )

       {

           Log.i("myapp", "startshiftactivitymodel = null");

           realm.beginTransaction();

           startshiftactivitymodel = realm.createObject(StartshiftActivityModel.class);

           realm.commitTransaction();

       }

       Log.i("myapp", "Vehicleregistration: " + startshiftactivitymodel.getVehicleregistration());

   }

    public StartshiftActivityModel getStartshiftactivitymodel() {

        return startshiftactivitymodel;

    }

    public void setStartshiftactivitymodel(StartshiftActivityModel startshiftactivitymodel) {

        this.startshiftactivitymodel = startshiftactivitymodel;

    }

    //Private instance of Model

   private StartshiftActivityModel startshiftactivitymodel;

   

   //Private Interface

   private Realm realm;

   

   //Public Interface

   public String getVehicleregistration() {

       return startshiftactivitymodel.getVehicleregistration();

   }

   public void setVehicleregistration(String vehicleregistration) {

     realm.beginTransaction();

     startshiftactivitymodel.setVehicleregistration(vehicleregistration);

     realm.commitTransaction();

   }

   public String getVehicleodometer() {return startshiftactivitymodel.getVehicleodometer();}

   public void setVehicleodometer(String vehicleodometer) {

     realm.beginTransaction();

     startshiftactivitymodel.setVehicleodometer(vehicleodometer);

     realm.commitTransaction();

   }

   public void onSubmit() {   

      if(getVehicleregistration().equals(""))

        {

            Toast.makeText(MainActivity.getContext(), "vehicleregistration missing", Toast.LENGTH_SHORT).show();

            return;

        }   

      if(getVehicleodometer().equals(""))

        {

            Toast.makeText(MainActivity.getContext(),"vehicleodometer missing", Toast.LENGTH_SHORT).show();

            return;

        }

   }

}
