I think maybe you've not published your process. As it happens baeldung has just recently released a new article illustrating this - http://www.baeldung.com/activiti-kickstart-and-rest-apps

Hi,

If you go throw Task App you have to click on Start after that to see your processes which you want to start.

Or you can simply deploy your App first by clicking on the + near the Identity Management

Do you mean that you want to restict the candidate for each of these user task so that the first user task has to be completed by a girl-home (i.e. any user who is both a member of both girl and home) and the second task to be completed by a girl-school user? If so I think you'd want to set candidate groups on the userTask - e.g. activiti:candidateGroups="girl, home". But I'm not 100% sure from your description whether you're talking about using groups to assign tasks or if you instead need one instance of a process for each user.

thank you for your replay

your's understand is right:

the first user task has to be completed by a girl-home (i.e. any user who is both a member of both girl and home) and the second task to be completed by a girl-school user

if i write

<userTask id="sid-54913B9F-9FA6-4A97-A6CB-5FF0D5F29F90" name="school and girl" activiti:candidateGroups="girl,school"></userTask>

any user who is a member of girl or home can claim this task

but i only need user who is both a member of both girl and home.

look at img :

I see, you want to capture intersection but listing groups gives you a union. In that case you could dynamically determine the set of users to be assignees using a piece of logic (as discussed in CandidateUsers from java code in BPMN or Dynamic assignment ). Or if it fits your case you could create groups that represent the intersections and use those.

thank's for you help again.

i used rest method to handle progress . so i can't write too many java code to control activiti.

In my opinion ,intersection is just as important as the union.because i'm a fish man in activiti,i guess that ,we can assign task to union group ,it also can assign to intersection group.

Thank you very much whatever.

If you did follow the lead of CandidateUsers from java code in BPMN or How to assign alfresco activiti workflow task to intersection of two or more groups? - Stack Overflow you'd be adding java logic for the engine to hook into. You wouldn't have to use the Java API to control the engine, it would be the engine using some Java. We're happy to discuss possible new features at Activiti/Activiti7 - Gitter
