Guided Procedure: Dynamical User Assignment at Runtime with WD API

Question

Hallo out there,
I'm trying to assign a user to a process role.
I set up my process in that way:
Process as root,
sequential block,
First action with callable Object,
Second action with callable Object,
It looks quite easy.
The callable Objects are embedded WD4J UI's and the data transfer GP Context, etc works fine
I'm still starting the process with the GP Designtime center, not via Webdynpro method (startProcess).
The following codesd snippets are placed in the execute method of the first callable object.
I guess a have to use the runtime methods.. not the designtime methods to assign the users
For example:
In Step 1 - execute Method: 
discovering the user for processing step2!
assigning the to the processrole depending for step2!
My Coding in step 1 looks like this:
First step: Getting the user infos:
//  Retrieve an IUser instance by a logon ID specified dynamically at runtime.
          IUser userStep1;
          IUser userStep2;
              userStep1 = UMFactory.getUserFactory().getUserByLogonID("user1");
              userStep2 = UMFactory.getUserFactory().getUserByLogonID("user2");
              IGPUserContext userContext;
              IGPUserContext userContext2;
                 userContext = GPContextFactory.getContextManager().createUserContext(userStep1);
              userContext = GPContextFactory.getContextManager().createUserContext(userStep2);
              IGPRuntimeManager rtm = GPProcessFactory.getRuntimeManager();
Now, i want to assign user2 to step2 :
   IGPProcess process =  GPProcessFactory.getDesigntimeManager().getActiveTemplate(
                      // by specifying its ID
                      processId,
                      // and the user accessing it
                      userContext);
             // create an empty role assignment list
             IGPProcessRoleInstanceList roles = rtm.createProcessRoleInstanceList();
             // get the process role number
             int rolenum = process.getRoleInfoCount();
             // iterate over the required roles
             for (int i = 0; i < rolenum; i++) {
           msgmr.reportSuccess("Anzahl der gefunden Prozessrollen: " + rolenum);
                // create a new role instance by specifying the role's unique name
                IGPProcessRoleInstance roleInstance = roles. createProcessRoleInstance(process.getRoleInfo(i).getRoleName());
   // add a user to the role instance
                roleInstance.addUser(userStep2);
                // add the new role to the assignment list
                roles.addProcessRoleInstance(roleInstance);   
I guess the problem is, that i call the wrong method to assign the user. I need to assign the user with following code snippet...
// dynamically assign a user to a role
rtm.addRuntimeDefinedUserToRole(
                  // process instance
                  prInstance,
                  // role name
                  "Processor",
                  // user that is assigned (IUser)
                  user,
                  // user context (IGPUserContext)
                  userContext);
// dynamically change the user assigned to a role for a particular task
String prInstanceID = prInstance.getID();
rtm.changeTaskProcessor(
                  // process instance ID
                  prInstanceID,
                  // activity instance ID
                  activityInstanceID,
                  // current user (IGPUserContext)
                  currentProcessorContext,
                  // new user (IGPUserContext)
                  newProcessorContext);
Thank you for any hint.
