I am trying to show a grid on a page with a toolbar immediately below the grid but I dont want to use the dockedItems .. instead i want to add a second component (toolbar) to the viewport and have that show up after the grid .. so i am using vbox layout but for some reason if i set the grid to forceFit: true then the grid disappears and only the bottom toolbar shows up .. but if i remove the forceFit:true then both show up but obviously the grid is not taking the full space available on the page ..
