Anylogic - Problem by Creating Schedule and ResourcePool programmatically - schedule

Question

Hier's the task, the agent "Machine" will be created programmatically via a excel data, and I need to create ResourcePool and Schedule for each machine programmatically which will set in a Service block.
I create two Variables and a function to create Schedule and ResourcePool like:
```
v_Workershift = new Schedule();
v_Workershift.setOwner(this);
v_Workershift.setCalendarType(true);
v_Workershift.setFirstDayOfWeek(MONDAY);
v_Workershift.setPeriod(1);
v_Workershift.setTimeUnits(DAY.toMilliseconds());
v_Workershift.setGlueIntervals(true);
v_Workershift.addInterval(1, 1, 6, 0, 0, 1, 1, 14, 0, 0, true);
v_Workershift.initialize();
//Create ResourcePool and Put the schedule"v_Workershift" into ResourcePool(v_WorkersPool)
v_WorkersPool = new ResourcePool();
v_WorkersPool.set_capacityDefinitionType(ResourcePool.CapacityDefinitionType.CAPACITY_SCHEDULE_ON_OFF);
v_WorkersPool.set_capacityScheduleOnOff(v_Workershift);
```
The function runs in the Agent "Machine" Startup and the setting in service like:
[enter image description here][1]
And there's the Problem:
there's a error by running the model:
```
Error during model startup:
root.pop_Machines[0].r_Workers:
Parameter capacityScheduleOnOff is not specified (null/empty)
```
Have i write the code correctly or i make a misstake by setting in the service block.
And could someone give me a advice, how to use the Help correctly, wenn i need to create another block programmaticly, i can only find some code in Forum, but not in Help.
Thank you very very much for your answer!

Answer 1

Couple of things to note here:
The error specifically mentions root.pop_Machines[0].r_Workers - it seems that this object still doesn't have a reference to the programmatically created Schedule object. In the first code snippet provided the Schedule object is set into v_WorkersPool object.
Creating objects programmatically is generally not advisable in AnyLogic. Things such as Schedule is fine because they're more or less standalone. However a ResourcePool is fairly complex and requires a fair bit of housekeeping to make sure it is created and registered correctly. Why is it necessary to create it programmatically?
Update
A better way to do this is to:
Put the new Schedule v_Workershift into a collection called schedules
Create a population of ResourcePool blocks (call it resources). Then instead of doing v_WorkersPool = new ResourcePool(); you can use v_WorkersPool = add_resources() which will create a ResoucePool and will also take care of all the housekeeping
Have the v_WorkersPool get Schedule from that schedules collection
