how to get the history of an work item?

You probably fetched the work item with only part of its properties, you can use IItemManager.fetchCompleteState() to get the full item in its historical state. If you want to get the full history you can also get all state handles at once using IItemManager.fetchAllStateHandles() instead of walking the history using IAuditable.getPredecessorState().

Thanks Christof! What you suggested worked great!

I have another question now. In addition to the previous states of the work item, I'm interested in *when* a given state was created. I did find a method "getModifiedBy" in the IWorkItem interface which tells me *who* created a state, but I wanted to know *when*. When I used the debugger to examine the state, I saw a field called "modified" which is the timestamp in the work item object, but this field is not exposed by the API. Is there a way to get this information from the API? (Apparently, I just couldn't even do a hack to cast the state to a WorkItemImpl, which defines the "modified" field of Timestamp type.)

Thanks!

You can use IItem.modified() (which returns a Date instead of a Timestamp).

I am using RTC version 3.0, and accessing JAVA api.

I am facing the following problem while trying to fetch the enumerations:

Code snippet:
IEnumeration<IPriority> enums = (IEnumeration<IPriority>)workItemClient.resolveEnumeration(attribute, null);


Also, the same error occurs, while doing following operation:
IWorkItemType workItemType = service.findWorkItemType(projectArea, "defect", new SysoutProgressMonitor());

Hello Christof,

I recently went through this post while trying to search any article that explains on reporting out of the history details. This post seems something similar. I would like to start writing reports that can fetch the changes of a work item along with the state changes. Could you please if there is a way I can achieve this, if so how?

Many Thanks,
Regards,
Sunita

 can you share the snippet for the same so that it will helpful for others also.
