I am using this code to assign task to another user.
lProcessService as ProcessService
bp as BusinessProcess
instF as InstanceFilter = InstanceFilter()
instanceDescription as String
connectTo bp
using url = Fuego.Server.directoryURL,
user = "super",
password = "super",
process = process.name
create instF
using processService = bp.processService
instF.searchScope = SearchScope(participantScope : ParticipantScope.ALL, statusScope : StatusScope.ONLY_INPROCESS)
addAttributeTo instF
using variable = "payDate",
comparator = Comparison.IS,
value = "abc"
instances as Fuego.Papi.Instance[] =getInstancesByFilter(bp, filter : instF)
for each inst in instances do
logMessage "assigning task to ANALYST.... "
reasign inst
using participant = "analyst"
end

Hi,
I uploaded a project to http://www.4shared.com/file/116623433/67e534c1/ManagerAssignsWork.html. Import this and see if might be what you're looking for.
1) In this project, a Manager ("mike") logs into the Workspace
2) Mike creates a work item instance by clicking on the "Create Inquiry" application.
3) The work item is created in the Manager's inbox (the instance is now in the Manager's "Assign to an Analyst" activity)
4) In the Workspace, the manager clicks on the "Assign to an Analyst" for the work item instance in his inbox
5) Because of the logic behind the "Assign to an Analyst" activity, the manager is prompted to pick the role and the specific Analyst"
6) Once the manager completes prompts for the analyst to assign it to, the work item instance flows to the "Review Request" activity in the Analyst role to the specific person the manager selected.
The logic that shows how to assign a work item instance to a specific participant in the process is inside the "Assign to an Analyst" activity in the process.
