Re: use ldap group in activiti

A little short on detail here.

What do you want to do with the group and is it the same LDAP server you are authenticating against?

Re: use ldap group in activiti

Why do you want to add the users to a group and then assign the group to the task?

Why not simply assign a list of users to the candidate users list?

I ask this because if you use a group and change the membership in one process instance, what happens if you have  second (or third, or 5 thousandth) process instance doing exactly the same thing to the same group?

What Im saying is that your design will almost certainly lead to conflict under load.

Re: use ldap group in activiti

actually i want to assign a task to a user which is not present in the candidate user list in the running workflow. 

Lets assume, a task is assigned to a user "A" but i want assign this task to another user "B" which is not present in flow as well as in candidate user list.

Give me the solution, how to do it.

Re: use ldap group in activiti

Dynamic assignment is simple as long as the user exists in the User repository.

Simply create a task Listener associated with the "assign" event (not create assign happens before create).

Inside the task listener add the following code:

task.assign(<theTaskIdIWantToUse>);

To be honest, in anything other than the most trivial processes, all task assignment is dynamic.

Re: use ldap group in activiti

Totally depends on your scenario.

Typically you would assign a task inside your process model or at least add candidate users there.

The claim action is meant to be used by candidate uses to take ownership of a task that is assigned to a group of users.

Re: use ldap group in activiti

yes its depends on my scenario.
i m successfully assign the task at run time  and its work fine.

but i have another question can we reassign a task to someone else user.

lets assume a task is assign to "user A" and we want to assign this task to "user B"  

i am using query to assign a task to "user A " is 

query is

 {"action":"claim","assignee":"userIdA"}

and rest url is 

http://localhost:8080/activiti-rest/service/runtime/tasks/taskId

what is the way of assign this task to a user B.?

Re: use ldap group in activiti

You must call the two REST APIs in order.

 

1. unclaim

POST runtime/tasks/%taskId%

{
"action": "claim",
"assignee": null
}

 

2. claim

POST runtime/tasks/%taskId%

{
"action": "claim",
"assignee": %userId%
}
