Conditional Sequence Flow evaluate to false delete the process instance

If possible to change the behavior of the activiti engine to throw a BPMError or simple don´t follow the sequence instead of delete the entire process instance.The alternative to this add a exclusive gateway, please some guide of this.

Hi,

I do not know what is your requirement and what do you expect.

If possible to change the behavior of the activiti engine

For sequence flow -> yes, you have to change behavior added to the activity during process definition parsing

Thank you, for your answer

For instance, when a sequence flow with a condition (${order == 2}) connect two user tasks without an exclusive gateway, and… when the condition is evaluated to false the entire process instance is delete from the workflow engine, the reason for deletion is the string "complete".

It is possible to throw an exception or doesn't allow to pass to the next task instead of delete the process instance from the runtime .

What actually happens is that, when an exception occurs, the process instance is rolled back to the previous stable state.
