Creating users from within anyObject workflow

Feder, Stephan Thu, 11 Jul 2024 06:45:00 -0700

Hello,

while evaluating syncope a problem has come up: I want to create users fromwithin anyObject workflow but it does not work as expected. In detail:


I have implemented

1. a FlowableAnyObjectWorkflowAdapter which is based on the existingFlowableUserWorkflowAdapter,


2. a task for creating anyObjects which based on the existing Create task,

3. an anyType

---
key: "myAny"
kind: "ANY_OBJECT"
classes: []

4. the task

public class CreateUser extends FlowableServiceTask {

    private final UserWorkflowAdapter userWorkflowAdapter;

    public CreateUser(final UserWorkflowAdapter userWorkflowAdapter) {
        this.userWorkflowAdapter = userWorkflowAdapter;
    }

    @Override
    protected void doExecute(final DelegateExecution execution) {
        userWorkflowAdapter.create(
            new UserCR.Builder("/", "test").build(),
            "creator",
            "context"
        );
    }
}

for creating users and

5. a workflow for anyObjects (ids of edges are removed)

<process id="anyObjectWorkflow" name="anyObjectWorkflow" isExecutable="true">
  <startEvent id="startevent1" name="Start" 
flowable:formFieldValidation="true"/>
  <sequenceFlow sourceRef="startevent1" targetRef="createAnyObject"/>
  <serviceTask id="createAnyObject" name="Create AnyObject" 
flowable:delegateExpression="${createAnyObject}"/>
  <sequenceFlow sourceRef="createAnyObject" targetRef="createUser"/>
  <serviceTask id="createUser" name="Create User" 
flowable:delegateExpression="${createUser}"/>
  <sequenceFlow sourceRef="createUser" targetRef="active"/>
  <userTask id="active" name="Active" flowable:formFieldValidation="true"/>
  <sequenceFlow sourceRef="active" targetRef="endevent1"/>
  <endEvent id="endevent1" name="End"/>
</process>

which, on create, creates the anyObject and additionally a user and stopsin a user task.

In the console, adding an instance of anyType "myAny" completessuccessfully but afterwards the console becomes partially unusable:


1. Opening the realms view gives Unexpected RuntimeException

Last cause: Unexpected character ('<' (code 60)): expected a valid value (JSON 
String, Number, Array, Object or token 'null', 'true' or 'false')
 at [Source: 
(org.apache.cxf.transport.http.asyncclient.AsyncHTTPConduit$AsyncWrappedOutputStream$7);
 line: 1, column: 2]
WicketMessage: Error attaching this container for rendering: 
[WebMarkupContainer [Component id = body]]

2. Trying to log in I always get "Wrong username and/or password".

This seems to by caused by

DEBUG [IO-1 task-2] org.springframework.security.web.FilterChainProxy           
 : Secured GET /actuator/info/
DEBUG [IO-1 task-2] 
ot.actuate.endpoint.web.servlet.WebMvcEndpointHandlerMapping : Mapped to

converting NullKeySerializer?) (through reference chain: 
java.util.Collections$UnmodifiableMap["numbers"]->org.apache.syncope.common.lib.info.NumbersInfo["usersByStatus"])]

which in turn is caused by the user's status being null:

{
  "_class": "org.apache.syncope.common.lib.to.UserTO",
  "key": "0190a1f1-4a18-7066-8783-278d63e87abd",
  "type": "USER",
  "realm": "/",
  "username": "test",
  "creator": "creator",
  "creationDate": "2024-07-11T13:17:43.953038683Z",
  "creationContext": "context",
  "lastModifier": "creator",
  "lastChangeDate": "2024-07-11T13:17:43.953038683Z",
  "lastChangeContext": "context",
  "dynRealms": [],
  "status": null,
  "auxClasses": [],
  "plainAttrs": [],
  "derAttrs": [],
  "virAttrs": [],
  "resources": [],
  "password": null,
  "token": null,
  "tokenExpireTime": null,
  "lastLoginDate": null,
  "changePwdDate": null,
  "failedLogins": 0,
  "securityQuestion": null,
  "securityAnswer": null,
  "suspended": false,
  "mustChangePassword": false,
  "relationships": [],
  "memberships": [],
  "dynMemberships": [],
  "roles": [],
  "dynRoles": [],
  "privileges": [],
  "linkedAccounts": [],
  "delegatingDelegations": [],
  "delegatedDelegations": []
}

And in fact, the status is never set:

WARN [IO-1 task-2] org.apache.syncope.core.flowable.impl.FlowableRuntimeUtils   
: While setting user status: unexpected task number (0)

So, what am I missing? Or is creating users from within anyObject workflownot supposed to work at all? Help would be appreciated.


Best Regards
