I have a requirement to dynamically set the assignee to tasks of process instance created from a process definition id.So,i get my assignee values from UI side and submitted for approval workflow.Now i will start the process and assign those assignee to the respective tasks.The problem is i get only one task on start of process as activiti gives only the current tasks/active tasks.As i don't get rest of task list i am unable to set the assignee to those tasks.
I also have to find pending tasks and completed tasks for a assignee from process instance,as there is query for task which i can use but as i am not able to set the assignee for all tasks ,this query seems not much of help for me.
So how can i get all tasks under a process instance and set the assignee to each user tasks and then complete the user tasks whenever needed using process instance and task query.
Below is my workflow
Workflow describing above scenario
To leverage the full power of the process engine, you would not pass runtime information at process start, you would dynamically determine the assignee at runtime, by using a taskListener on the „create“ event.
But if you have to stick to your approach: put the assignees in a map with the taskDefinitionKey
As key and pass that map to the process instance as process variables.
Afterwards, in your Bpmn model use „${taskDefintionKey}“ in the assigned field (taskdefkey being the I’d of your user task of course).

Basically I want two tasks, I want the second task (Task B) to look at the status of first task (Task A).
All the examples I see use yaml, within the Release section of setting up deployments, they all use a user interface.
If I use Agent.JobStatus in Step A or Step B, it shows the Job Status of what we are currently in. I figure I need to capture the value between Task A and Task B (not within either one), how does one capture that? I either can't find it, or not understanding something.
I have put it in the agent job variable expression of Task B....hoping it gathered what was the last job status, but it is null.
in(variables['Agent.JobStatus'], 'Failed', 'SucceededWithIssues')
I have used one multi instance subprocess which includes an workflow with human task. When executing, its creating the number of human tasks as to the number of elements present inside the collection object. But all tasks have same process instance id. How the relation is working between parent process and multi instance subprocess?
If there are multiple elements in collection list, then it will create those many tasks inside the multi instance sub process. As all the tasks have same process instance id, how to identify the respective process variable values for each task and the uniqueness of each flow afterwards? And is there a way to make it create an different instance id for each task of the multi instance subprocess?
I did not get all the question, but I will try to answer what I got:
Human tasks have their own task instance id
What is collection object? If you mean tasks in bpmn model, then it is as expected: process instance flow starts after start node and when it reaches a human task, it will create an task instance with id. You can see it in the tasks in UI and with api you can claim, work on, complete , populate data etc.
it is wise to have a separate/different variable for every tasks that can execute in parallel. Then the input will be kept in distinguished data placeholders and you can use it accordingly.
you can create a different instance(task instance) for each task or have repeatable tasks
well the answer was to put the multi-instance into a sub-process, this will allow me to have a separate process instance id per each element of the my List (the input of the multi-instance )
I have a Task Group that I created out of a set of build tasks. I am able to edit the tasks quite well, but i now realise i will need to add another parameter to the task group. How do I go about doing that?
Task group parameters are automatically created based on the variables used in the tasks. If you reference a new variable in a task that's within a task group, it will pop up.
In addition to the accepted answer, if you want to add parameters that are not directly referenced by tasks within the tasks group (e.g. to use in a config file token replacement task) then you can export your task group, edit the .json file then import it back in. The parameters are in an inputs array near the end of file. You can also hide parameters here if you only want to use them internally to the task group by setting a default value and adding a 'visibleRule' property, see this article for details: https://medium.com/objectsharp/how-to-hide-a-task-group-parameter-b95f7c85870c
This will create a new task group rather than updating your current task group. If you want to update the task group, you can use this REST API:

There is a way to pass the candidate users dynamically to Activiti workflow as described in .
How do I pass a list of candidate users to an activiti workflow task in alfresco?
When candidateUser/candidateGroup is set for a UserTask using a variable, when is the expression evaluated ? Is the task id -> user/group persisted in database for fast query of like, list all the tasks a particular use can claim ? What table is it stored in ?
When human tasks are created there are two distinct events that fire.
Create : When the task itself is created and most of the task metadata is associated with the task.
Assign : When the task assignment is evaluated and the task is assigned to either an assignee or candidateGroup.
As such, the candidateGroup expression is evaluated during the assign phase.
This means we can easily manipulate the list of candidates based on a rule, database result or some other business logic prior to the task actually being assigned using a task listener that fires on the create phase.
Hope this helps,
G
Concerning the "What table is it stored in ?" part of your question:
Candidate start groups/users for a given task or process are stored in the ACT_IDENTITY_LINK table.
I am tying to implement the following algorithm with Quartz and not really sure if it can be done. This is my first attempt at using quartz.
User notification Job - This job computes a monthly report and emails to a user, it expects a user id and other parameters that are used to generate the customized user report
There are potentially 10,000+ of these reports that need to be generated
Monthly Job to figure who needs reports Fires
search the database to look for users that need to be sent a monthly report
for each user found create a jobDetail that will compute the monthly report and deliver it to report sender that takes care of sending the report
schedule each of the jobDetails from step 2 to execute right after this job finishes
What I have not been able to figure out.
How to make sure that monthly job executes in a single transaction so that all users that need a monthly report are identified and jobs are scheduled to notify them
How to schedule a job right away to execute right after the job that created them?
I am using Spring 3.2 an Quartz 2.1
Nice use case for quartz usage.
You can try sheduling a new job from within the job class. This can be possibly with by creating a new jobdetail and trigger from inside execute() method.
