We return to
the question on how
to combine multiple transactions into one undo with a new answer by Arnošt Löbel, ex Senior Principal Engineer of the Revit development team
– How do I know how many transactions, and which ones, are assimilated into group?
– What if I start a transaction before starting a group (in the same API context) and then call
Assimilate, will this ahead started one also be assimilated into the group?
– I can leave the API context (external event or
Execute method) with the transaction group still open...
