ACT_HI_VARINST table - TASK_ID_

lixkid

Hi,

My goal is to get all HistoricVariableInstances with specific taskId from ACT_HI_VARINST table, but every row in that table (which represents HistoricVariableInstance) is set to NULL.

Is there a way to associate process variable with a task which might result in TASK_ID_ (in table ACT_HI_VARINST) column being set to appropriate value?

I'm using Activiti Engine 5.11.

What is your history level? For variable history, you need to set it higher than default.

What is your history level? For variable history, you need to set it higher than default.

Even after I changed property "history" (in the definition of processEngineConfiguration bean in activiti.cfg.xml) by setting it to "full" with the following code:
<code>
<bean id="processEngineConfiguration" class="org.activiti.cdi.CdiJtaProcessEngineConfiguration">
   …
   <property name="history" value="full" />
   …
</bean>
</code>

values in column TASK_ID_ (table ACT_HI_VARINST) are set to NULL.

Do you please have any other suggestions?

I have found a solution to my problem in this post .

In order for task id to be saved in TASK_ID_ column (table ACT_HI_VARINST), it needs to be associated with process variables by using the following code:
<code>
taskService.setVariablesLocal(task.getId(), vars);
</code>
