Hi.

I created microservice with jhipster. I added to it activiti 7.0.0.Beta1. My microservices are configured to use jhipster UAA. I added a small endpoint to create process instance:

    @Timed
    @GetMapping("/start")
    public ResponseEntity<ProcessInstance> start() throws URISyntaxException {
        Offer offer = new Offer();
        StartProcessPayload payload = ProcessPayloadBuilder
                .start()
                .withProcessDefinitionKey(PROCESS_NAME)
                .withProcessInstanceName("New offer")
                .withVariable("offer", offer)
                .build();
        ProcessInstance instance = processRuntime.start(payload);
        return ResponseEntity.created(new URI("/api/process/start/" + instance.getId()))
                .headers(HeaderUtil.createEntityCreationAlert(PROCESS_NAME, instance.getId()))
                .body(instance);
    }

And it works perfectly. :) But when I try to expose list of current users task in this way:

    @GetMapping("/get-my-tasks")
    @Timed
    public ResponseEntity<List<Task>> getAllMyTasks(Pageable pageable) {
        log.debug("REST request to get a page of my tasks");

        org.activiti.runtime.api.query.Pageable.of(new Long(pageable.getOffset()).intValue(), pageable.getPageNumber());
        Page<Task> page = taskRuntime.tasks(
                org.activiti.runtime.api.query.Pageable.of(new Long(pageable.getOffset()).intValue(), pageable.getPageNumber())
        );

        HttpHeaders headers = ActivitiPaginationUtil.generatePaginationHttpHeaders(page, "/api/tasks/get-my-tasks");
        return new ResponseEntity<>(page.getContent(), headers, HttpStatus.OK);
    }

I get exception:

For me seams that spring-boot inject InMemoryUserDetailsManager but i dont know why. Should I send this issue to jhipster team or it is activiti problem ?

Also when I change my code a little bit:

    @Timed
    @GetMapping("/start")
    public ResponseEntity<ProcessInstance> start() throws URISyntaxException {
        Offer offer = new Offer();
        StartProcessPayload payload = ProcessPayloadBuilder
                .start()
                .withProcessDefinitionKey(PROCESS_NAME)
                .withProcessInstanceName("New offer")
                .withVariable("offer", offer)
                .withVariable("owner", SecurityUtils.getCurrentUserLogin().get())
                .build();
        ProcessInstance instance = processRuntime.start(payload);
        return ResponseEntity.created(new URI("/api/process/start/" + instance.getId()))
                .headers(HeaderUtil.createEntityCreationAlert(PROCESS_NAME, instance.getId()))
                .body(instance);
    }

In the database I will have owner variable set to correct user login.

EDIT: Ok, I figured it up. But this is only for my POC so it is not a solution:

@Configuration
public class ActivitiUserDetailsConfiguration {

    private final Logger log = LoggerFactory.getLogger(ActivitiUserDetailsConfiguration.class);

    @Bean
    public UserDetailsService myUserDetailsService() {

        InMemoryUserDetailsManager inMemoryUserDetailsManager = new InMemoryUserDetailsManager();

        List<SimpleGrantedAuthority> authorities = new ArrayList();
        authorities.add(new SimpleGrantedAuthority("ROLE_ADMIN"));
        authorities.add(new SimpleGrantedAuthority("ROLE_USER"));
        authorities.add(new SimpleGrantedAuthority("ROLE_ACTIVITI_USER"));

        inMemoryUserDetailsManager.createUser(new User("admin", passwordEncoder().encode("admin"), authorities));

        return inMemoryUserDetailsManager;
    }

    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }
}

We have a process with 14+ async tasks that are mutually inclusive (need to run one after the other)

The reason for async is to be be able to get a processInstanceId returned when starting the run.

Currently, throw/catch signal event handling in Activiti engine causes race conditions behavior to occur when throw/catch signals are used to synchronize parallel activities in the same process instance scope.

For example, after a parallel gateway, due to various task execution timings or non-deterministic execution path by Activiti engine, a signal on one path is emitted before subscribers on parallel paths can subscribe to it, causing subscribers to block and wait indefinitely:

To fix this problem, the PR introduces throw signal event registration in the process instance session execution context. This will allow subscribers to receive events at any time after the signal has been published, so the execution can proceed if the signal has been registered in the current session or, has already been recorded in the historic activity instance audit log in the previous sessions.

Global events handling stays the same as before, i.e. non-deterministic, because it requires global persistent event registration/cleanup mechanism in the command execution session to properly synchronize between parallel process instances for each tenant.

See test cases in Activiti Engine module for details: SignalEventSessionManagerTest.java

Query service uses Keycloak realm to resolve user groups via Rest for every task list request using https://github.com/Activiti/activiti-cloud-service-common/blob/448c871049dcececd7df279c4613e32966f3f22f/activiti-cloud-services-common-identity-keycloak/src/main/java/org/activiti/cloud/services/identity/keycloak/KeycloakUserGroupManager.java#L87 .

Because JWT access token does not contain the list of effective user groups:

{
  "jti": "bcd08573-d4d5-4ad8-8c65-8913e9388ec5",
  "exp": 1558536769,

    "account": {
      "roles": [
        "manage-account",

      ]
    }
  },

  "name": "h r",
  "preferred_username": "hruser",
  "given_name": "h",
  "family_name": "r",
  "email": "[email protected]"
}

It is not optimal to do that for every request, because it is slow and impacts overall response time when calling Rest Apis.

Another problem is that Keycloak Admin client is instantiating RestEasy Http Client with default connection pool of maximum 10 connections:

https://github.com/keycloak/keycloak/blob/da85cff53b239250fa880e086b2721ba41a9a1e8/integration/admin-client/src/main/java/org/keycloak/admin/client/Keycloak.java#L72

This configuration creates ThreadPoolExecutor with limited number threads in the pool which will cause blocking with more than 10 concurrent requests:;

This is likely the reason of a connection timeout when Task Controller tries to connect to Keycloak to extract realm data to get user roles.

To solve this problem we can use Keycloak User Groups mapper to inject the list of user groups into extra claims inside JWT token below.

Must what works?

1. start SIGNALS_CHAIN process
2. trigger trigger message
3. process done

Actually process waits for ev2

ActivitiSignalsChainFeatureTest.testSignalsChain.bpmn.zip

Reason, agenda&commandInvokers walks throught process bypassing wide. And when ev2 fired, ev2 catchEvent not exists yet.

There is some strange with flow.

In one process that pattern works fine. In second does not works. In that test also does not works with exclusiveGateway added.

FYI. I have create a simple process definition like this:

And then I start a process instance of this process definition, but for some reason the upper service tasked failed and cause the entire JVM process exit, I want to know how I can resume this process instance execution when I restart the program, is there any API for me to do this? Also if I can resume this process instance execution, where this process instance will start execute? from the failed activity? @jbarrez @tijsrademakers really hope to get your help, thanks very much :)

I have a problem use ParallelGateway in Activiti 6.0. i try various combinations by async = true/false and exclusive = true/false for ServiceTask , but my process still wait(block), and I found some debug log:

o.a.e.i.c.ExecuteAsyncJobCmd Job does not exist anymore and will not be executed. It has most likely been deleted as part of another concurrent part of the process instance.

but i found the job record in ACT_RU_JOB table, it looks like one thread insert the job record , other thread read the job record in the same times. how could I fix that ?

Thanks & Regards

Our process runs normally within four or five days after the service is started, but there will be an end of the interruption after four or five days on the line, and no reason can be found.We suspect that it was an error when the process parsed the XML file gongxun5.txt

I tried to get Activiti from this update site https://www.activiti.org/designer/update/ but it is no more available, then i tried to download the zip file from here http://www.activiti.org/designer/archived/activiti-designer-5.18.0.zip and also i got a negative result "Page not found" can anyone give me the new updatesite if it exists? thanks.

Apparently the MANIFEST.MF in the 5.13 release version of 'activiti-engine' is technically invalid; incorrect, and should not pass even the initial parsing stage. The present mechanism for build validation likely contains a less strict facility for manifest parsing -- as the manifest contains a wildcard-like entry, "org.activiti.osgi*" which should not be present.

Incidentally, I discovered this as Eclipse Virgo choked on activiti-engine-5.13.jar when I dropped it into 'repository/usr'. The activiti-engine-5.13.jar file was just one of 42 total dependency files I was deploying; all others imported correctly. Some snippets of the log are shown below, along with a shell command which identifies the offending line number within the manifest.

• Notice the entry, "org.activiti.osgi*"

The jar file was pulled via Maven, from http://maven.alfresco.com/nexus/content/repositories/activiti

        </dependency>

Also found a verify similar issue (which was since fixed) for Jersey; https://java.net/jira/browse/JERSEY-1426 .

Meanwhile, can anyone suggest a workaround? I know I could manually fix the manifest, but not sure just what to replace this entry with.
