Generally this type of error will occur when multiple users have access to an object on a list and one of them works it, then another attempts to work it after it has been completed.

Yes the multiple users are assigned to a workitem. Is there any solution for this other than force restarting??

Why would you force restart? That doesn't make sense to me.

This is what I think the situation is:

You have workitems W1, W2, W3 assigned to Users U1 and U2.

U1 Displays their worklist and sees the following:

W1 Ready
W2 Ready
W3 Ready

They select W1 and begin to work it.

Now U2 displays their worklist and sees the following:

W2 Ready
W3 Ready

U2 selects W2 and begins to work it.

Now U1 Checks in W1 and is returned to the worlist which will not be refreshed, so what they see is:
W2 Ready
W3 Ready

And if they try to work W2 they will get either "Invalid State" in the case where U2 has not completed W2 yet, or "Object not found" in the case where U2 has already completed W2.

The moral of the story is you either need to train your users to refresh, or use the WebClient option which automatically does the refresh. I can see no case where you would want to do any force finish or force restart.

I have tested a sample one.....it was me alone working on that workitem....

when i refresh i still see the workitem on my list. when i accept that item it gives that error.....so what to do now....that is the reason i have done force restart.......this error of object empty was sporadic....now a days it is more with workitems....so wanted to find the solution for it??

As u said, one of the reason it might be. Then what abt the above example one I tested where no other user was working had the problem.....
Any suggestions???

Hi,
maybe this technote solves your problem:
