Then, inside the repetition, modify the tag to be

where HighlightConditional is a WOConditional bound to a
method that
returns true only when the selected index equals the
current index.
How do I call this method to check for when the selected index
equals the current index? Should I place a WOGenericElement which
calls the method inside my row, so that the check can be performed
on each iteration of the repetition? I have a feeling that there
are more efficient ways, I just don't know them yet.
That's what the WOConditional is for. The WOConditional is inside
the WORepetition, so it will get evaluated once each time through the
repetition. Most rows, the condition will evaluate to false, and
therefore the style="background: grey;" will not show up; on the row
that the selected index == the repetition index, the WOConditional
will evaluate to true and that particular row will have
style="background: grey;".
So the WOConditional should have its condition binding set to, say,
isSelected(). In isSelected(), simply return repetitionIndex ==
selectedIndex; where repetitionIndex is an ivar bound to the
WORepetition's index binding and selectedIndex gets set by your
SELECT action method.
Does that make more sense?
