Permissions issue when process area is a project area

Permissions seem to work only when the user is at team area level but not at project area level i.e. when the process area is a project area, permissions do not work but when the process area is a team area, permissions work.Can some one suggest what is missing in the following code?

//get all the process areas i.e. either a project area or team areas to which the user belongs in this project
IProcessArea[] processAreas = processService.findProcessAreas(currentUser, projAreaHandle,
null);


if (processAreas.length > 0) {

System.out.println(processAreas.getName());

createOperation = new AdvisableOperation(OPERATION_ID_GETPLANS,
null, processAreas) {

@Override
public IOperationReport run(
IBehaviorConfiguration configuration,
IProgressMonitor monitor)
throws TeamRepositoryException {


return null;
}

@Override
public String[] getActions() throws TeamRepositoryException {
return new String[] { ACTION_ID_PLAN };
}

};

IServerProcess serverProcess = processServerService
.getServerProcess(processAreas);

IOperationReport report = serverProcess
.adviseAndExecute(createOperation);
System.out.println(report);
}
//if the user does not belong to any team area or even the project area
else
{
throw new TeamRepositoryException(null, "You are not a member of this project");
}
