With the new <dotj:editmode> tag, you can provide inline row editing that will allow the user to edit a row's
data in a very easy manner. This must be combined with an equivalent edit action on the grid's Action Bar. If a
<dotj:editmode> tag is not specified, then a simple HTML textual input field is used. If the dotJ HTML form
tags are used, then field validators can be used. This is very polished since it enforces validation on the field when
the user is editing it. Try it - the Last Name and First Name columns require a value in the field.
