hi, i've noticed that after creating two separate tasks (different names) for the same user below query return 2x2=4 items from which two of them are duplicates minaClient.getTasksAssignedAsPotentialOwner("user","language",responseHandler) List tasksOwned = responseHandler.getResults(); I've checked database and in fact there are only two rows in a Task table but the above API calls multiple outer joins on different tables that cause duplicates to be produced. So, if this is an "intentional bug" and it is up to the calling method to get rid of duplicates is there any other better/more efficient way of working with tasks as it seems like the whole API is somehow flawed. I suspect that with significant number of tasks the performance will be very low -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/Drools-Flow-client-ge...
