Steve Lawrence commented on DAFFODIL-2364:
------------------------------------------
My guess is that means we are incrementing the array index when we shouldn't
be? For example, in SequenceParserBases.scala, we have this code to increment
the array index each time we parse an element of an array:
{code:scala}
if (ais ne Done) {
pstate.mpstate.moveOverOneArrayIndexOnly()
}
{code}
Seems like maybe that need an extra condition, and it should only call that
function if we actually added an array element. I think if resultOfTry is
AbsentRep it essentially means we parsed something but nothing was added to the
infoset, and thus shouldn't increment the array index?
