How to create stand-alone user task with local variables

andrey_nikolov — Mon, 18 Jul 2016 23:40:28 GMT

I am trying to create a stand-alone user task which is not associated with any process instance. How could I create local variables to be associated with the new task?Using the code below we can create and persist the task, but the last call 'CreateVariablesLocal' causes 'lazy loading outside comman

Hi Andrey,

have a look on org.activiti.engine.test.api.task.TaskServiceTest#testSaveTaskUpdate in activiti source.

Hi Martin,

The distributable activiti-engine-5.21.0.jar does not have package org.activiti.engine.test.api so we cannot check the code.

However we found a work-around: create each variable individually (setVariableLocal) instead of creating them in bulk (createVariablesLocal) by passing variables map.

This is somewhat counter intuitive and looks like a bug. Please investigate and advise if we should raise a ticket.

Once again, thanks for your response!

<code>
TaskEntity taskEntity = (TaskEntity) taskService.newTask();
taskEntity.setCategory(…);
taskEntity.setDescription(…);
taskEntity.setDueDate(…);
taskEntity.setName(…);
taskEntity.setOwner(…);
taskEntity.setPriority(…);
taskEntity.setTenantId(…);
taskService.saveTask(taskEntity);
for (… each variable) {
taskService.setVariableLocal(… task ID, … variable name, … variable value);
}
</code>

Hi Andrey,

this test is on Activiti6 (sorry) But there should be similar in Activiti5.
bug:
createVariableLocal must be called inside the command context.
