Sync Smart Panel Values w/ Current Row in Grid

Hello,

I am currently trying to open up a smart panel based on values in a grid on the row selected. Unfortunately, the values are not being updated on the filterview (a series of unbound fields I have) when I open it using PXFormula. It works when I open up the first row, but then after that, it doesn’t update with subsequent rows selected. 

To remedy this, I try to update my PXFilter view before running .AskExt.. and it works to update the values, but once I do this it won’t save the updated values. See below for code:

        public PXAction<ModifyDialog> Modify;
        [PXButton(CommitChanges = true, DisplayOnMainToolbar = false)]
        [PXUIField(DisplayName = "Modify")]
        protected void modify()
        {              
          if (UpdateModifyView() != true ||ModifyDialogView.AskExt(true) != WebDialogResult.OK) return;
          else { ModifyActivity(); }       
        }

        private bool UpdateModifyView()
        {
            EPActivityApprove modTPActivity = TimesheetView.Current;
            if(modTPActivity is null) return false;

            PMTimeActivityExt modTPActivityExt = modTPActivity.GetExtension<PMTimeActivityExt>();
            if(modTPActivityExt is null) return false;

            ModifyDialogView.Current.TimeIn = modTPActivity.Date;
            ModifyDialogView.Update(ModifyDialogView.Current);
            return true;
        }

        private void ModifyActivity()
        {
            EPActivityApprove modTPActivity = TimesheetView.Current;
            if(modTPActivity is null) return;

            PMTimeActivityExt modTPActivityExt = modTPActivity.GetExtension<PMTimeActivityExt>();
            if(modTPActivityExt is null) return;            

            //Get Activity
            EmployeeActivitiesEntry graphActivity = PXGraph.CreateInstance<EmployeeActivitiesEntry>();
            graphActivity.Clear();

            graphActivity.Activity.Insert(modTPActivity);
            modTPActivity.Date = ModifyDialogView.Current.TimeIn;
            graphActivity.Activity.Update(modTPActivity);
            graphActivity.Actions.PressSave();

            EmployeeFilterView.Current.Status = "CI";
            EmployeeFilterView.Update(EmployeeFilterView.Current);            
          }  

So two ways I’m hoping someone can get me input..

• If I use PXFormula to update the PXFilter values.. how can I ensure it refreshes based on the row selected (see below for my current field declaration).

            #region TimeIn
            [PXDateAndTime]
            [PXFormula(typeof(Current<PMTimeActivityExt.usrBlyTimeIn>))]
            [PXUIField(DisplayName = "Time In")]
            public virtual DateTime? TimeIn { get; set; }
            public abstract class timeIn : PX.Data.BQL.BqlDateTime.Field<timeIn> { }
            #endregion

• If not, why is my code not updating the graph when I don’t call the modifycurrentfilter vs when I do.
