How to add array of sth as param for operaration

[koral]

I have a class Class1 with operation Operation1. Also I have another class Class2.
I need to add input parameters to Operation1 - first is string and second is array of objects of class Class2. How to setup multiplicity on second parameter?

When you define Class1::operation1, save the operation, then click the "Edit" button next to Parameters to edit the parameters.
In the resulting dialog add each input parameter.  There is a button for Multiplicity on this parameter definition dialog.  I don't think it is possible to display this multiplicity on the diagram.  (This is build 1009.)
