Acquire Location with Sort By not working as expected

[ FlexSim 22.0.13 ]

Hi,

I am trying to make a dynamic Location Acquire where the group acquired changes according to the patient coming in. This works with a custom code within the Location resource.

Then when I try to sort the group members (which are multi locations) by labels, the patient do not acquire the least occupied chairs as reproduced in the test model attached.

I do not know how to make this works although it seems simple. Can anybody help me ?

In the case of multilocations, the objects that get acquired are the individual drawsurrogates.

You correctly take this into account when incrementing/decrementing the label. However you also have to keep this in mind for the order expression. Since the drawsurrogates are the objects that get acquired, they are also the ones to be queried, so you have to shift the reference to their parent object first before reading the label.

Great ! It worked. Thank you @Felix Möhlmann

I tried before to use up.up.up but I did not have the value.as(treenode) before it.
Could you explain to me what is usable in the Sort By field ? What is value in this case ?

[moehlmann_fe]

In theory you should be able to use any FlexScript expression since the content gets pasted directly into a query string (I think). "value" is the thing that gets queried, so in this case the individual chair objects. That "value" needs to be cast as a treenode in the first case I honestly only found out through trial and error.

Ok ! Wonderful. Thank you very much @Felix Möhlmann .
