Make custom fields editable on Journal Transaction details

@Naveen Boga solved this problem for me before on the SO Lines grid

However, that was to enable native fields.  I’m using the same logic to try to enable two custom fields on the GL entry details, but I am unable to make them editable.

I’ve added what I think is the necessary code and changes to the workflow.  

namespace PX.Objects.GL
{
  public class JournalEntry_Extension : PXGraphExtension<PX.Objects.GL.JournalEntry>
  {
    #region Event Handlers

    protected void GLTran_RowSelected(PXCache cache, PXRowSelectedEventArgs e, PXRowSelected InvokeBaseHandler)
    {
      if(InvokeBaseHandler != null)
        InvokeBaseHandler(cache, e);
      var row = (GLTran)e.Row;

      if (row != null)
      {
        //Allowing caches to update with below code
        Base.BatchModule.Cache.AllowUpdate = true;
        Base.GLTranModuleBatNbr.Cache.AllowUpdate = true;

        GLTranExt glExt = PXCache<GLTran>.GetExtension<GLTranExt>(row);
        PXUIFieldAttribute.SetEnabled<GLTranExt.usrLoan>(cache, row, true);
        PXUIFieldAttribute.SetEnabled<GLTranExt.usrALE>(cache, row, true);
      }
    }



    #endregion
  }
}

Data is being saved to the DB, so there is nothing wrong with the fields:

I’ve no idea why this isn’t working.  It is almost a copy/paste from the solution from Naveen for SO Lines.

I’ve attached a copy of the project if anyone wants a closer look.
