Below is my code in WorkItem Save precondition.

//getServices
IWorkItemServer workItemServer = getService(IWorkItemServer.class);

IWorkItem workItem_newstate = (IWorkItem)saveOperation.getNewState().getFullState();
Identifier<IState> workItemNewState = workItem_newstate.getState2();
IWorkflowInfo workflowInfoNew = workItemServer.findWorkflowInfo(workItem_newstate, monitor);
String stateName_new = workflowInfoNew.getStateName(workItemNewState);


How can I get the previous (history) state of the workitem? I am having hard time to figure this code out.

There are only two forum entries, but it is very hard to figure out the API part

Hi
To get to the previous item states of the work item, you can use

RepositoryItemService#fetchAllStates
an for each of these handles you can do:
RepositoryItemService#fetchState

Then you have a work item where you can read the workflow state as you do in your code snippet.

I'm trying to retrieve a previous state of an Auditable. If I have the UUID of the state I'm looking for, is there a way to retrieve this state directly, rather than doing IRepositoryItemService.fetchAllStates and iterating through to find the item with the right state? I was thinking I could maybe create an item handle and set the state on that, then fetch the item, but there doesn't seem to be an API to set the state. Thanks!

Hi
You can use the corresponding IItemType to do this. E.g. for a work item handle:
IWorkItem.ITEM_TYPE.createItemHandle(Object origin, UUID itemId, UUID optionalStateId);
