You didn't post your xml correctly.

Why do you want to do this without xml?
The MultiInstanceActivityBehavior can only be used in the context of a process, not standalone.

Hello Jbarrez,

Sorry for incorrect xml .
I uploaded xml file please find the attachment.

currently i am creating the workflow using XML files . Bt as per client requirement i want to create dynamically.

So is there a way to create multinstance tasks like this.? Bt i do not want to use xml
and want to create multinstance tasks.

Activiti does not support adding dynamically new tasks to it, nor creating them up front without xml im afraid.

The only thing that Activiti supports is creating 'standalone' tasks through the taskService, but they are not related to process instances directly as regular tasks are.

You mean something like http://stacktrace.be/blog/2013/03/dynamic-process-creation-and-deployment-in-100-lines/ ?

Hello Jbarrez,

Thanks.

I wan't to that using simple table driven definitions but again the table driven definitions has very limited set of classes so i have decide to use bpmn modeler classes as specified in your refrrence link.

In Dynamic Process Creation:- how can i create the one task for multiple user ??

Thanks.

how can i create the one task for multiple user ??
You could assign task to user's group (e.g. candidateGroups attribute in task).
