Activiti 6: Cannot Cancel Process

chrisx_212 — Mon, 14 Mar 2016 07:58:34 GMT

Everytime I try to cancel a process in Activiti 6, I get this message:### Error updating database. Cause: com.mysql.jdbc.exceptions.jdbc4.MySQLIntegrityConstraintViolationException: Cannot delete or update a parent row: a foreign key constraint fails (`activiti6`.`act_ru_execution`, CONSTRAINT `ACT

Can you post the process XML and also what method calls you're doing exactly?

The method I'm calling is the Runtime Service's Delete Process Instance.

I've tried the following test on the v6 master:

<code>
public class MyUnitTest extends PluggableActivitiTestCase {

@Test
@Deployment(resources = { "org/activiti/test/test.bpmn20.xml" })
public void test() throws Exception {
org.h2.tools.Server.createWebServer("-web").start();

ProcessInstance processInstance = runtimeService.startProcessInstanceByKey("two-step-process");
assertNotNull(processInstance);

runtimeService.deleteProcessInstance(processInstance.getId(), null);
assertEquals(0, runtimeService.createExecutionQuery().count());
}

}
</code>

And that succeeds.

Is that also what you tried to do?

Sorry for not replying for long. I came across to another problem based on this.

I ended up modifying the bulkDeleteStatement in DbSqlSession by creating new queries and deleting all child elements first before deleting the parent one. It worked… except that when the command was instead 'Complete Task' instead of 'Cancel Process', things got deleted as well (they flushed the delete commands even as I tried 'Complete Task').

How do we differentiate the command so it's Cancel Process, not Complete Task?

Not sure I'm following? How are using triggering complete task instead of cancel … ?
