I do not how this happened, and trying to solve the problem.
When the workitem was checked out, the value of all data container changed from another instance. Data mapping is correct, correct values are displyed in correct elements, but the entire data is from different instance. How this possible? Is anyone experience similar problem? |

I have never heard of anything like this... and I would doubt that what you say is actually happening. If it is, you should open a PMR _________________ John McDonald

Is it possible that the user and/or user interface changed the data? I have seen that happen and it is very confusing. |

From the application, input container is copied to output container
with 2 elements are modified, other than that all remain.
Most of instance are OK, and can not re-produce error to test.
It just happens unexpectedly and get 2 different instances (with different data) end up with same data. |

Sounds like an application problem
You should use the data default connector on the activity to copy data from the input container to the output container so that your application only has to worry about data elements that have changed (it also insulates your applications from data container structure changes). |

Copying input to output (at check-in) by the application is working fine.
The problem happens when checked-out. when the item was checked out, input container values are already swapped from previous values with different data from another instance. |

Like I mentioned, problem is not updating element.
All values are placed at the correct elements in the structure.
Entire container value is from different process instance. |

We faced the same problem too..We raised a PMR but still unable to reproduce the problem consistently...There is another post "Container values changing" which is the same problem too. Any updates will be appreciated. Will post the solution if we find one.
I feel this could be a flaw in the Workitem id , might be I am wrong. |

In our case we are using stuct to struct mapping so its unlikely to be adata mapping, more over the entire container set has a different set of values.
I thinks thats what everyone lese is facing...Weird |

Like I said initially, I have never seen anything like this, and I assume this is an application issue. You say you suspect it is something with the Workitem id. WHY?
Do you have your own client, or are you using the IBM supplied client? _________________ John McDonald

I am not 100% sure...its just a possblity. This is happening once in a while..We are processing 1000's of workitems in a day. It has been reported more than a couple of times in a month. So, first of all it is not consistent and we are unable to comeup with a pattern.
We are using the persistent OID when we check out to check it back in.
We are planning analysing the out put on this front, Might be an unintended work item is getting checked in with the containers of the current workitem.
It is difficult to say,its just my guess. |

BTW we are using our own client, not the IBM supplied one. But we are more or less sure that it isnt an application problem though we havent ruled it out. We are analysing in this front too |

I am not sure how this persistentoid is generated. Is it from a database column or some where else? Does any one know how this is done? |

Persistent OID is not stored in the database, there is a class called OIDGenerator (I THINK) that is not documented that can produce what is referred to as the External OID (this is the Persistent OID) given the database columns representing the Internal OID (i.e the database column). The doc for this class was once found in the Support pac WA0C, I do not know if it still exists there or not.
My guess is that this is an application problem. If you have an open PMR on this, if this was a known problem I believe you would have a solution by now.
And I doubt that a bug like this could go unnoticed for long. _________________ John McDonald

Thanks John. Yes the supoport pac still exists and is supported with both 3.5 and 3.6. |
