L3 - Default Description
Given:
- Process with an non-interrupting conditional EventSubProcess
When:
- Process instance is created with variables which triggers this event process
Then:
- History for all given variables are not written.
Observation:
It seems that the Listener which writes the history for the variable events is not called.
This is because ExecutionEntity#isAutoFireHistoryEvents returns false in ExecutionEntity#getVariableInstanceLifecycleListeners.
Please see the attached unit test and process model to reproduce this bug.
Example:
RuntimeService runtimeService = processEngineRule.getRuntimeService();
Map<String, Object> variables = new HashMap<>();
variables.put("startTimer", 1L);
variables.put("duration", "PT2S");
final ProcessInstance processInstance = runtimeService.startProcessInstanceByKey("sample", "0815", variables);
TaskService taskService = processEngineRule.getTaskService();
Task task = taskService.createTaskQuery().singleResult();
if (task != null) {
assertEquals("init process", task.getName());
taskService.complete(task.getId());
}
assertEquals(processEngineRule
.getHistoryService()
.createHistoricVariableInstanceQuery()
.count(), 2L); // fails
Workaround:
RuntimeService runtimeService = processEngineRule.getRuntimeService();
Map<String, Object> variables = new HashMap<>();
// variables.put("startTimer", 1L);
variables.put("duration", "PT2S");
final ProcessInstance processInstance = runtimeService.startProcessInstanceByKey("sample", "0815", variables);
runtimeService.setVariable(processInstance.getProcessInstanceId(), "startTimer", 1L);
TaskService taskService = processEngineRule.getTaskService();
Task task = taskService.createTaskQuery().singleResult();
if (task != null) {
assertEquals("init process", task.getName());
taskService.complete(task.getId());
}
assertEquals(processEngineRule
.getHistoryService()
.createHistoricVariableInstanceQuery()
.count(), 2L);
