How to get OIM workflow waiting for a task successfully completed?

Question

The requirement is to get OIM provisiong workflow pending and wait for a external status ready. When the external status not ready, I return "REJECTED" which mapped to "P" in "Task->Reponse" tab. Meanwhile, in the "Task->General" tab, I set the "Retry Count" to 5 and "Retry Period in Minutes" to 1.
I have hoped that once the task return "REJECTED", the workflow enter status "Pending". One minute later, the task re-instanced by OIM to have another check for whether the external status ready. If ready, return "COMPLETED". If not yet, return "REJECTED" and workflow re-enter pending. And on and on, until to max to 5 times attempt. But in fact, OIM workflow never attempt to re-enter the task again after the 1st time "REJECTED" returned.
How to do with this?

Use the code snippet below to get the task status. Based on this you can filter rejected tasks.
userintf = (tcUserOperationsIntf) ioUtilityFactory.getUtility("Thor.API.Operations.tcUserOperationsIntf");
provintf = (tcProvisioningOperationsIntf)ioUtilityFactory.getUtility("Thor.API.Operations.tcProvisioningOperationsIntf");
long userKey=100;
tcResultSet userresultSet = userintf.getObjects(userKey);
for(int i=0;i<userresultSet.getRowCount();i++)
     userresultSet.goToRow(i);
     long processKey = userresultSet.getLongValue("Process Instance.Key");
     tcResultSet provresultSet = provintf.getProcessDetail(processKey);
     for(int j=0; i<provresultSet.getRowCount();j++)
          provresultSet.goToRow(j);
          String taskName = provresultSet.getStringValue("Process Definition.Tasks.Task Name");
          String taskStatus = provresultSet.getStringValue("Process Instance.Task Details.Status");
