Hi,

In my Java simple client I perform some changes in a workitem and saving it.
like this:
try
{
IDetailedStatus s = workingCopy.save(null);
}
catch ...

In some case I get the following exception. and no clue about what causes it.
Trying to perform the same operation in my eclipse RTC client - all is working fine.

(I'm using RTC 2.0.0.2)

The exception trace:

Could you post the snippet of code that creates or updates the work item?

Any chance that the owner of your work item is 'null'?

Right! that's it.

I should set the owner to "Unassigned" contributor.

Thanks.
