activiti - Activiti: Unable to read a task variable(defined in process definition) in listener

Question

In process definition, I have a user task for whihc I have defined a variable as:

<userTask id="myTask" name="myTaskName" activiti:actionType="coding"....>

I have a listener to read the variable:

VariableInstance myVariable = taskService.getVariableInstanceLocal(delegateTask.getId(),"actionType");

But it returns null.

I also tried with:

String actionType = (String)taskService.getVariableLocal(delegateTask.getId(),"actionType");

This too returns null.

How to get actionType in listener?

为什么要使用getVariableLocal()方法的两个参数？只需要一个参数，即您自定义的属性名称。

你应该使用它task.getVariableLocal("customAttributeName");来获得它的价值。

希望能帮助到你。
