[M_abugabal]

I have business scenario where i need some user in form to select multiple users to get in parallel their feedback

So I need sample that contains the following

1- Form with control that allow user to search in system users and select few of them

2- Multi Instance Parallel User task for the selected users and 

3- Some way to store in variable their concatenated feedback

Thanks

I would be difficult to put up code for your req. here are some links to help you:

1. https://docs.alfresco.com/process-services1.11/topics/example_3_dynamic_pie_chart.html
2. https://hub.alfresco.com/t5/alfresco-process-services/parallel-multi-instance-dynamic-task-candidate...
3. just access your variables using task.getVariable(..) and set your execution.setVariable(...)

Hope that helps.

Thanks for your reply

But i need more clarification regarding the mult instance task issue

I have created user task and configured it as the following

Multi instance type to parallel

And set the collection varaible , element varaible and assignment to the same element variable

Should the collection contains the users ids or names and how it will be formatted?  comma seperated ?

and how can i get id for some user mail??

no, collection variable must hold a collection (e.g. ArrayList<String>) with the useIDs. the user ids from email can be obtained using UserService. the element variable (does not need to be declared or initialized) has to be a string variable that you can use in assigment using MVEL expression. e.g. if element variable is set as userId, then you can use it in assignment as ${userId}
