Viewing process variables in activiti explorer

einszwo — Thu, 23 Apr 2015 06:57:33 GMT

Hi all,I`m new to activiti.I have a simple business process which is integrated and executed by my own application. I try to view active and already executed (finished) process instances via the activiti explorer.Of course the avtiviti explorer and also my own application point to the same database.

Hi Markus,
activiti stores runtime variables in the runtime tables.
When you are looking for variables (and their changes - depends on the history level) for already completed processes use history tables.

Hey Martin,

I understand this concept and my process vars are stored in the ACT_HI_VARINST Table.
But my question is why are they not shown in completed process instance part of activity explorer (Administration part)?

Ok I try to to change my question.

Is it possible to view process values of already executed process instances (completed) in activiti explorer.
The processes are executed in my own application but it points to the same db as the activiti explorer.

Yes, in the admin section of the Explorer completed process instances can be viewed. If the process variables are not using primitive types, but Java class types there might be a classpath issue.

Best regards,

Hey ,

what do you mean with class path issue. How can I show process variables which type is one of my domain objects in activiti explorer.
Must the explorer know about this java class? Is there some kind of tutorial or guide ?

Best regards

> what do you mean with class path issue.

It means the classes of the variable type need to be on the classpath (ie the jar needs to be in the /lib or similar).

Hey,

For active project instances it works perfectly. I am able to view process variables of complex java types.

Unfortunately I am not able to view the process variables of finished process instances. No error occurs. There is only a message that no variables exists for this process instance. Could it be a bug in the explorer?

Best regards

Yes, it could very well be. Could you check if there the entries are in your database for the completed process instance?
