MultiStaleDataException when saving the work item

0
Kinny Kun (51●8●3) | asked Apr 20 '09, 1:51 p.m.
Hi,

Im getting MultiStaleDataException when saving the work item. The exception occurs after I tried to set attribute and save the work item couple times. Following is the code how I set the attribute and save the work item. Any idea what may cause the exception? What did I do wrong in the code? Please help. Thanks.

Any help is appreciated. Thank you very much.

IWorkItemClient wiClient = (IWorkItemClient) repo.getClientLibrary(IWorkItemClient.class);
IWorkItemWorkingCopyManager wcManager = wiClient.getWorkItemWorkingCopyManager();
IWorkItemHandle handle = (IWorkItemHandle)workitem.getItemHandle();
ItemProfile<IWorkItem> profile = IWorkItem.FULL_PROFILE;
wcManager.connect(handle, profile, monitor);
WorkItemWorkingCopy workingCopy = wcManager.getWorkingCopy(handle);
IWorkItem wi = workingCopy.getWorkItem();
wi.setValue(attr, attrValue); (**note: attr is IAttribute and attrValue is Object)
IDetailedStatus s = workingCopy.save(monitor);

I think the exception is being caused because the work item you are referencing has already been updated from a previous change and you are still referencing the old work item.
So let's say you are updating multiple attributes but each independently. The pseudo-code would be something like this ...

get work item handle
get working copy
edit attribute 1
save working copy

get fresh copy of work item
get working copy
edit attribute 2
save working copy

get fresh copy of work item
... 



// get fresh copy

		workItem = workItemServer.findWorkItemById(workItem.getId(),

				IWorkItem.FULL_PROFILE, monitor);

Actually the problem might be, that after doing: 

wcManager.connect(handle, profile, monitor);

A disconnect should be performed. Else you will always access the same work item (cached) on subsequent calls to the manager: 

public void disconnectWCPYManager(IWorkItemHandle wihdl)
{
    getWorkItemClient().getWorkItemWorkingCopyManager().disconnect(wihdl);
}
