This technique works for me. In fact I'm a little surprised I never thought of using "reverse()" before, since that seems a bit more efficient than the "length(save!value)" method I used in the past. Can you verify that your individual gridRowLayouts have valid "id" values? 
 a!gridLayout(
 headerCells: {
 a!gridLayoutHeaderCell(label: "label")
 },
 selectable: true(),
 selectionValue: ri!selection,
 selectionStyle: "ROW_HIGHLIGHT",
 selectionSaveInto: {
 a!save(
 ri!selection,
 index(reverse(save!value), 1, null())
 )
 },
 rows: {
 a!gridRowLayout(
 id: 1,
 contents: { a!richTextDisplayField(value: "dummy row 1") }
 ),
 a!gridRowLayout(
 id: 2,
 contents: { a!richTextDisplayField(value: "dummy row 2") }
 )
 }
)

Grid selection works with multiple values. To limit it to one, there is no direct way and you have to manipulate the value in your code. Try the below code in your saveInto 
 saveInto: {
 local!value,
 a!save(
 local!value,
 index(local!value, length(local!value), {})
 )
 }
