Lock Gone Exception
Lock Gone exception is being logged in logs , Below is the use case details.
>> Try to upload the spreadsheet through model dialog .
>> performing obj-save on work page in post activity of model dialog , but it's giving an error for 1 object out of 50 objects.
we haven't heard any compliance from the user while processing the object but exception was logged in logs.
Generally it occurs when trying to perform obj save on unlocked object, but how to identify when lock is being released for an object. Any possible scenario to cause this exception?
I'm going to do two things to get rid of this exception ,
>> Remove obj-save and external commit on work object instance from post activity so submitModelFlowAction will take care of work object transaction operation.
>> if object changes needs to be save on fly then we do obj-Refresh-Lock if lock is not held on object.
Please suggest here if any suggestion to get rid of below exception.

Hi,
Even we had a similar error in one of our applications. We tried using Obj-Refresh-And-Lock and did Obj-Save, but it didn't help. May be because the user has the workitem open and we are trying to acquire the lock and it never happened?
