        }
    });
    viewManager.showPopupWindow(popup);
}

Example 2 with TaskService

use of org.activiti.engine.TaskService in project Activiti by Activiti.

the class ProcessDefinitionInfoCacheTest method testDeployRevisedProcessAfterDeleteOnOtherProcessEngine.

public void testDeployRevisedProcessAfterDeleteOnOtherProcessEngine() {
    // Setup both process engines
    ProcessEngine processEngine1 = new StandaloneProcessEngineConfiguration().setProcessEngineName("reboot-test-schema").setDatabaseSchemaUpdate(org.activiti.engine.ProcessEngineConfiguration.DB_SCHEMA_UPDATE_TRUE).setJdbcUrl("jdbc:h2:mem:activiti-process-cache-test;DB_CLOSE_DELAY=1000").setJobExecutorActivate(false).buildProcessEngine();
    RepositoryService repositoryService1 = processEngine1.getRepositoryService();
    ProcessEngine processEngine2 = new StandaloneProcessEngineConfiguration().setProcessEngineName("reboot-test").setDatabaseSchemaUpdate(org.activiti.engine.ProcessEngineConfiguration.DB_SCHEMA_UPDATE_FALSE).setJdbcUrl("jdbc:h2:mem:activiti-process-cache-test;DB_CLOSE_DELAY=1000").setJobExecutorActivate(false).buildProcessEngine();
    RepositoryService repositoryService2 = processEngine2.getRepositoryService();
    RuntimeService runtimeService2 = processEngine2.getRuntimeService();
    TaskService taskService2 = processEngine2.getTaskService();
    // Deploy first version of process: start->originalTask->end on first process engine
    String deploymentId = repositoryService1.createDeployment().addClasspathResource("org/activiti/engine/test/cache/originalProcess.bpmn20.xml").deploy().getId();

    // Delete the deployment on second process engine
    repositoryService2.deleteDeployment(deploymentId, true);
    assertEquals(0, repositoryService2.createDeploymentQuery().count());
    assertEquals(0, runtimeService2.createProcessInstanceQuery().count());
    // deploy a revised version of the process: start->revisedTask->end on first process engine
    //
    // Before the bugfix, this would set the cache on the first process engine,
    // but the second process engine still has the original process definition in his cache.
    // Since there is a deployment delete in between, the new generated process definition id is the same 
    // as in the original deployment, making the second process engine using the old cached process definition.
    deploymentId = repositoryService1.createDeployment().addClasspathResource("org/activiti/engine/test/cache/revisedProcess.bpmn20.xml").deploy().getId();
    // Start process instance on second process engine -> must use revised process definition
    repositoryService2.createProcessDefinitionQuery().singleResult().getId();
    runtimeService2.startProcessInstanceByKey("oneTaskProcess");
    task = taskService2.createTaskQuery().singleResult();
