How do I get workitem details out of WorkItemHandleImpl ?

Yehil, I would suggest to search the Extensions Workshop.

It depends on what you do and where (Client extension, Plain Java client Libraries or Server extension)
An extension should extend AbstractService which provides important operations such as getAuthenticatedContributor() and getService() to get services that are listed in the prerequisites.

You use AbstractService.getService(Class<T> class) so

IAuditableCommon common = (IAuditableCommon) this.getService(IAuditableCommon.class)

Clients and client extensions you get Client Libraries using

IAuditableClient auditableClient = (IAuditableClient) iTeamrepository.getClientLibrary(IAuditableClient.class);

The API often returns object handles instead of the full object
–To get the object from an IHandle use a resolve operation provided by the Services/Client Libraries. Objects might not be resolvable due to permissions. There are differences in the server and client API:

Server API uses services
        IAuditableCommon.resolveAuditable(handle, profile, monitor)
        IAuditableCommon.resolveAuditablesPermissionAware(handles, profile, monitor)
Example:
IWorkItem workItem = auditableCommon.resolveAuditable((IAuditableHandle) handle,IWorkItem.SMALL_PROFILE, monitor);     

Client API uses Client Libraries.
        IAuditableClient auditableClient = (IAuditableClient) repository.getClientLibrary(IAuditableClient.class);
        IWorkItem workItem = auditableClient.resolveAuditable((IAuditableHandle) handle,IWorkItem.FULL_PROFILE, monitor);       
 
On the client side the ItemManager provides the ability to resolve/fetch an item from a handle:
        ITeamrepository.itemManager().fetchCompleteItem(itemHandle, flags, monitor)

Profiles are used to determine how much data needs to be loaded when resolving a handle
–General profiles: ItemProfile.createFullProfile(IProjectArea.ITEM_TYPE)
–Special profiles: IWorkItem.SMALL_PROFILE, IQueryDescriptor.FULL_PROFILE
–On the client ItemManager flags are IItemManager.DEFAULT (cached), IItemManager.REFRESH (refresh cache)

Sometimes it is necessary to find the team repository containing an object; use getOrigin()
 ITeamRepository repository = (ITeamRepository) iItem.getOrigin();

 Hi Ralph,

That is what is there. I would suggest looking at the error in the log and to add that service to the prerequisites as described in the workshop. You add it in the plugin.xml.

Like:
