List of process instances via REST returns empty processvariables

trond_nordli

I'm trying in the latest version 5.13 of Activiti to access process-instances via REST-API. It works well except the processvariables is missing.

It works on list of task as expected:

/runtime/tasks?includeProcessVariables = true
‍‍‍

But don't work on list of process:

/runtime/process-instances?includeProcessVariables = true
‍‍‍

Where you only get blank values "variables": []
And the processvariables can successful be accessed thru variable directly.

/runtime/process-instances/{processId}/variables/{variable}
‍‍‍

Seems that the docs are not up to date with the actual implementation. The includeProcessVariables is ignored, so that's why the list is empty…

Thanks for the answer, looking forward to a version which has implemented this.

This is fixed on master, so the next version that is released will contain this functionality.

I'm on 5.14 and still see the same thing.
I'll try 5.15 to see if it is fixed.

ssun

Nope! Update to 5.15 did not work at all. The variables is always an empty array! We need to make one extra call with /variables added to the end of process instance or task url. Can we fix this and avoid making a lot of calls when list process instances or tasks?

Thank you!

I downloaded the latest source code from here https://github.com/Activiti/Activiti/tree/master/modules/activiti-webapp-rest2
I built a war file and it does not list variables at all.
Also somehow the one I build returns XML instead of JSON.

I take back my previous comments. Added ?includeProcessVariables=true worked, I mistakenly added includeVariables

I'm not following here: are you sating the includeProcessVariables does not return the variables in the response?
