You might want to consider instead using a Screenflow for this. Screenflows manage the flow from one presentation to another presentation better that the show method does.
1. They let you see visually (vs. hidden inside a method) what presentation is flowing to another presentation and
2. Unlike the show method, once you flow to a presentation inside a screenflow you can always go back to earlier presentations in the screenflow. You lose the context once you flow using a show method.
Here's the logic I think you're looking for. It's fairly common to use a show method for BAM Dashboard presentations. Here I have a BPM Object called "Order" in the module "Dashboards". To invoke a presentation called "OrderList" inside this BPM Object from another BPM Object's method, you could use logic like this:
order as Dashboards.Order = Dashboards.Order()
// this passes in the value of the customer's type into the other BPM Object's presentation
order.customerType = this.customerType
show this
    using instance = order,
          presentationName = "OrderList"Normally, logic like this would be invoked from a push button or an on click event (the "On Click" property) on a BPM Object dashboard widget (e.g. bar chart, pie chart or gauge).
Hope this helps,
