Details

• I simply removed the prop type validation from the component. This of course is not a fix in itself, but I figured since every other FunctionalGridViewField component also does not have prop type validation we might as well remove it from the FunctionalGridViewFieldDate component in order to be consistent. That has the added benefit that there will be no more prop type errors when converting.
• The prop type validation fail did not have any impact on user experience before.
