Does 'taskVariableValueEquals' method does not work?

Tested in version 5.13:My BPMN Process (simpleprocess.bpmn):<?xml version="1.0" encoding="UTF-8"?><definitions xmlns="http://www.omg.org/spec/BPMN/20100524/MODEL" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:activiti="http://activiti.org/bpmn" xmlns:bpmndi="http://www.omg.org

When you do the query on a task variable (which is a local scoped variable) you should use setVariableLocal instead of setVariable.

Best regards,

Thanks trademak!!

With <code>taskService.setVariableLocal(task.getId(), "var_name", "var_value");</code> the result is OK.

I add my JUnit to test the scope of variables (in case anyone finds it of interest):

<code>
…
TaskService taskService = activitiRule.getTaskService();
RuntimeService runtimeService = activitiRule.getRuntimeService();

// Get Task
Task task = taskService.createTaskQuery().singleResult();
assertNotNull(task.getId());

String executionId = task.getExecutionId();
String taskId = task.getId();

// Task Variable Scope:
// Global –> Execution Level (parentId == executionId)
// Local –> Task Level (parentId == taskId)

// Set Variables
runtimeService.setVariable(executionId, "var_exec_global", "var_value"); // (parentId == executionId)
runtimeService.setVariableLocal(executionId, "var_exec_local", "var_value"); // (parentId == executionId)
taskService.setVariable(taskId, "var_task_global", "var_value"); // (parentId == executionId)
taskService.setVariableLocal(taskId, "var_task_local", "var_value"); // (parentId == taskId)

// Get Execution by variable
Execution exec = runtimeService.createExecutionQuery().variableValueEquals("var_exec_global", "var_value").singleResult();
assertNotNull(exec);
exec = runtimeService.createExecutionQuery().variableValueEquals("var_exec_local", "var_value").singleResult();
assertNotNull(exec);
exec = runtimeService.createExecutionQuery().variableValueEquals("var_task_global", "var_value").singleResult();
assertNotNull(exec);

// Get Task by variable
Task task2 = taskService.createTaskQuery().taskVariableValueEquals("var_task_global", "var_value").singleResult();
assertNull(task2); // <==== NULL
task2 = taskService.createTaskQuery().taskVariableValueEquals("var_task_local", "var_value").singleResult();
assertNotNull(task2);

// Get global variables with RuntimeService
Object value = runtimeService.getVariable(executionId, "var_exec_global");
assertNotNull(value);
value = runtimeService.getVariableLocal(executionId, "var_exec_global");
assertNotNull(value);
value = runtimeService.getVariable(executionId, "var_exec_local");
assertNotNull(value);
value = runtimeService.getVariableLocal(executionId, "var_exec_local");
assertNotNull(value);
value = runtimeService.getVariable(executionId, "var_task_global");
assertNotNull(value);
value = runtimeService.getVariableLocal(executionId, "var_task_global");
assertNotNull(value);

// Get global variables with TaskService
value = taskService.getVariable(taskId, "var_exec_global");
assertNotNull(value);
value = taskService.getVariable(taskId, "var_exec_local");
assertNotNull(value);
value = taskService.getVariable(taskId, "var_task_global");
assertNotNull(value);

// Get Local Task variables
value = taskService.getVariableLocal(taskId, "var_task_local");
assertNotNull(value);
…
</code>

Have a nice day.
