Hi,
I am using JAVA APIs to initiate a workflow and assign a task to a group called 'Analyst' which I have already created in the GUI.While doing so I am getting the following exception
Pooled actors value 'Analyst' is invalid
although I am able to assign a task to a single assignee.
When the workflow is kicked off,we are passing some parameters to the workflow node as
parameters.put(WorkflowModel.ASSOC_POOLED_ACTORS, "Analyst");
However while passing a single assignee as parameter in the above line like
parameters.put(WorkflowModel.ASSOC_ASSIGNEE, "admin");
the workflow gets initiated successfully.
As per my guess this is where I am making a mistake.However I have no idea how to resolve it.Any suggestions will be greatly appreciated.Thanks in advance
I have installed Alfresco 2.9B version on Windows XP and using MySQL database.
