I think there are a couple of problems with your implementation.

First, your unit test should make use of the formService rather than setting the execution variables.

Next, I think you need to use JUEL expressions (#) rather than delegate expressions ($) in your form property.

Take a look at the FormServiceTest.testFormPropertyExpression(), it demonstrates how to map data into a pojo.
If after you look at this it still doesnt work, create a unit test and attach to the forum thread so we can take a look.

Thanks,

Greg

Thank you for your answer.

In some point i use deferred expression (#{}) instead of immediate expression (${}) but it doesn't work. Anyway, reading the JUEL documentation I should using deferred expression since it is used for set and get while the immediate is only suitable for get, so i will change.

I gonna test the formService thing, thank you again.

Finally it works, I modified the bpmn to use the deferred expression in the form and the unit test to use formService.

test.bpmn

<process id="Test" name="Test" isExecutable="true">
<startEvent id="start" name="start">
<extensionElements>
<activiti:executionListener event="start" class="cl.pardo.business.BusinessLogic"></activiti:executionListener>
</extensionElements>
</startEvent>
<userTask id="dataEntry" name="Data Entry">
<extensionElements>
<activiti:formProperty id="name" name="Name" type="string" expression="#{entry.name}"></activiti:formProperty>
<activiti:formProperty id="accept" name="Accept" type="boolean" expression="#{entry.accept}" required="true"></activiti:formProperty>
</extensionElements>
</userTask>
<exclusiveGateway id="exclusivegateway1" name="Exclusive Gateway"></exclusiveGateway>
<serviceTask id="acceptedMessage" name="Accepted Message" activiti:expression="${business.AcceptedMessage()}"></serviceTask>
<serviceTask id="rejectedMessage" name="Rejected Message" activiti:expression="${business.RejectedMessage()}"></serviceTask>
<endEvent id="end" name="end">
<extensionElements>
<activiti:executionListener event="end" expression="${business.end()}"></activiti:executionListener>
</extensionElements>
</endEvent>
<sequenceFlow id="accept" name="Accept" sourceRef="exclusivegateway1" targetRef="acceptedMessage">
<conditionExpression xsi:type="tFormalExpression"><![CDATA[${business.isAccepted()}]]></conditionExpression>
</sequenceFlow>
<sequenceFlow id="reject" name="Reject" sourceRef="exclusivegateway1" targetRef="rejectedMessage">
<conditionExpression xsi:type="tFormalExpression"><![CDATA[${!business.isAccepted()}]]></conditionExpression>
</sequenceFlow>
<sequenceFlow id="flow4" sourceRef="rejectedMessage" targetRef="end"></sequenceFlow>
<sequenceFlow id="flow5" sourceRef="acceptedMessage" targetRef="end"></sequenceFlow>
<sequenceFlow id="flow6" sourceRef="start" targetRef="dataEntry"></sequenceFlow>
<serviceTask id="persistData" name="Persist Data" activiti:expression="${business.persistData(entry)}"></serviceTask>
<sequenceFlow id="flow7" sourceRef="dataEntry" targetRef="persistData"></sequenceFlow>
<sequenceFlow id="flow8" sourceRef="persistData" targetRef="exclusivegateway1"></sequenceFlow>
</process>

the unit test

@Test
public void startProcess() throws Exception {
RepositoryService repositoryService = activitiRule.getRepositoryService();
repositoryService.createDeployment().addInputStream("Test.bpmn20.xml", new FileInputStream(filename)).deploy();
RuntimeService runtimeService = activitiRule.getRuntimeService();

ProcessInstance processInstance = runtimeService.startProcessInstanceByKey("Test");
assertNotNull(processInstance.getId());
LOGGER.info("id {} {}", processInstance.getId(), processInstance.getProcessDefinitionId());

TaskService taskService = activitiRule.getTaskService();
FormService formService = activitiRule.getFormService();

Task task = taskService.createTaskQuery().singleResult();
LOGGER.info("TASK NAME: {}", task.getName());
Map<String, String> formData = new HashMap<String, String>();
formData.put("name", "Benjamin");
formData.put("accept", "false");
formService.submitTaskFormData(task.getId(), formData);
// taskService.setVariable(task.getId(), "name", "Benjamin");
// taskService.setVariable(task.getId(), "accept", true);
taskService.complete(task.getId());
}

Than you.
