The datagrid should be displayed with editable empty fields.

You need to set a dataprovider for the datagrid. You need an ArrayCollection that holds all the (newly added) entries from the user plus an empty entry. When you initialize the dataprovider it has to contain the empty entry, otherwise there will not be the possibility to "add" a new entry via the grid because the grid only allows to edit the existing entries. So after the user begins to fill the empty entry, you have to add a new, empty entry to the dataprovider.
