How to use a custom function to order by in zone queue strategy ?

I would like to order the entrance of tokens by theirs labels. Choice 1 : Duration, Choice 2 NbEtapes (Model Parameters).

I would like to use a custom function to determinate de queue strategy in the zone. But the error message :

"syntax error, unexpected identifier Object, expecting end of code. Make sure commas, parentheses, etc. are placed correctly".

1) How to use the custom function ind the Zone Queue strategy field ?

2) I would like to controle the order, by cloning the result in a globale table for exemple. Is this possible ?

Thanks in advance

You can do this by setting the node to an option value using the OnSet of the parameter:

zone-orderby-customrequest_jl.fsm

To see the result I would use a statistics collector to detect tokens entering the zone. You can query that as if it were a global table.

@Nicolas M25, if this code gets precompiled, then variable requete is empty. Maybe you can assign instead the else assigned value as default declared value.

I don't think that field is evaluated to find an expression for the order by clause, it uses the value as the order by clause.
