There is no declarative method (that is, only using annotations), but
you should be able to define class to use setter:
public void setMyPropA(List<String> values {
// keep track of what has been populated, assign appropriately
}
and it will actually get called multiple times, once per sequence of
contiguous values.
But you will need to track state yourself, possibly by initializing
fields appropriately or
adding a separate state-tracking field (initialized in constructor).
I hope this helps,
