Tibco Ebx - Triggers on Data Context

[Sanchit Sood 2]

On one of my datacontext variable I am storing the PKs of all the records created. I am using trigger to set the value of datacontext variable and using getInternalParameters and setInternalParameters to save this varibale.

The issue if, If I update and record that was created in first step later on, then the data context variable deletes all the previous stored PKs and save the record that has been modified.

InteractionHelper.ParametersMap object=sessionInteraction.getInternalParameters(); this returns null in this case.

How do i persist my previous PKs as well as the new PKs on that data context variable
