Get History Detail ID on Creation about activiti HOT 5 OPEN

Which Activiti version are you using? If pre 7.x then those versions are no longer maintained.

Hi sorry, we are using version 7.1.0.M3.1, I have updated my original question.

from activiti.

Thanks for adding the version info.

The save history endpoint is void rather than returning the newly added HistoricDetail entity.

Which endpoint? Can you point to that endpoint in the code?

from activiti.

Endpoint may have been a little misleading, allow me to try to clarify...

We are calling the updateTask endpoint from our application. And since we have history level set to FULL, the following method gets executed which inserts our variables into the activiti history detail table.

This is working as we expect, however this method has void return type, when we are actually interested in the ID that gets returned after line 650. For example, you can see the ID we are interested in being returned with the HistoricDetailVariableInstanceUpdateEntity here:

but just not with the method and therefore not to our application. I understand making this method no longer return void looks like it would have tons of consequences so that seems unlikely and probably unnecessary.

Right now we are experimenting with making a query to the history detail table after our record gets inserted, and grabbing the latest ID for the variable we are interested in. We are concerned this won't work as we test our more complicated workflows with more tasks/subtasks, and ideally we would like to grab the ID right after DB insertion.

We discussed potentially writing our own HistoryManager Implementation that would override this method and write the ID to ThreadLocal so we could access it from our application. This was our best idea at the moment.

Would love to hear if you think we are on the right track, or any other ideas you may have. Thanks!

Have you tried using HistoricVariableInstanceQuery?

You can use it to get the latest variable update filtering by taskId, variableName, etc!
