I have a question about a best practise concerning processes with a dynamic list as a variable.

Let's say for example i have an process which has to store 0..* objects as variables. I.e. an process B

public class B{

     string b1;

     string b2;

     java.util.Collection<A> aCollection;

}

and a class A

public class A{

     string a1;

     string a2;

}

so before calling

executionService.startProcessInstanceByKey("B-process-name", variables);

I have to fill the variables map. But how should i add aCollection ? Should i do something like

variables.put("b1", someBObject.b1);

variables.put("b2", someBObject.b2);

for (int i=0 ; i<someBObject.aCollection.size() ; i++){

     variables.put("aCollection[" + i + "].a1", aCollection.get(i).a1);

     variables.put("aCollection[" + i + "].a2", aCollection.get(i).a2);

}

Or maybe there is a better/cleaner solution.

Or should i store these object in my own tables, and just store a reference (id) on the variables list ?

Thanks for any replies
