11g BPM - Setting instance data of a running process instance

Question

Hi,
What is the recommended pattern for interrupting a running process instance and changing an instance variable (data object) ?
Scenario is:
- process instance is launched with an interactive to look at the instance data
- an event is triggered, effectively interrupting the instance and changing the instance data
- next time the user opens the screen for the interactive the data has changed
Any help much appreciated.
cheers
Tony

Hi Dan,
Hope all is good with you. Thanks for the response.
I am using 11.1.1.6 and have tried a few things, one of which was using an event subprocess and correlations but it didnt change the Data Object as I expected. Maybe I got something wrong and will try again. So you expect the following to work:
- Create a simple process with one string data object, a correlation and one interactive showing the data object.
- Map the correlation to an input parameter
- Set the string data object to some initial value
- Create an event subprocess of the above in the automatic handler swimlane (starts with a message and ends with nothing)
- have the implementation of the start message take a string and an id
- map the id to the correlation
- map the string to the data object in the subprocess
- Create the simple process from Enterprise Manager passing in a correlation id
- View the interactive in the BPM Workspace and see the initial string
- Use EM to fire the event subprocess passing the same correlation id and a new string
- View the interactive in the BPM Workspace and see the new string
so, if you set the data object in the event sub process, it is the same value as the initial instance ? or have I misunderstood ?
I will give it another go, just checking my understanding...
cheers
