Since we upgraded from Activiti 5.17 to 6.0.0, OWNER_ column in ACT_HI_TASKINST is null and not data not persisted in database.
I set task owner in TaskListener with java:
delegateTask.setOwner((String)execution.getVariable("task_owner")); The OWNER_ data set properly in
ACT_RU_TASK but not in ACT_HI_TASKINST. I tried TaskListener for create and also tried for completion, both not work.
Another task property: CATEGORY_ has the similar problem,
delegateTask.setCategory((String) execution.getVariable("entity_type")); worked fine in 5.17, but not saved in 6.0.0.
Figured out CATEGORY_ can be saved into ACT_HI_TASKINST if I set that in task main config as in the screenshot.
But I have not found a way to make OWNER_ saved in ACT_HI_TASKINST. Do any body have this kind of problem? I do need some your help.
