I am trying to get all the "_PreviousValues" of a field.

For example, the state of a defect have changed from "Open" => "Fixed" => "Closed".

I would like to get all history of the state, but not just the previous value.

Thanks!

LookbackAPI returns historic versions (snapshots) of objects. To get a history of state transitions you need to get all snapshots where transition happened, which can be achieved by using "_PreviousValues.State":{"$exists":true} condition.

  • Follow up: I managed to get the data using the lookbackapi based on the selected release(release combobox). Now, I am trying to display the parsed data using a grid. When the select event fires from the combobox, it takes 2-3 seconds for the grid to display the loading... gif. I am wondering if there is a way to display that loading gif as soon as the select event fires. – user2099986 Aug 26 '14 at 16:24
  • Found the setLoading function on the grid. THANKS – user2099986 Aug 26 '14 at 18:05
