Working with Human Task Service

Question

Hello everybody,
I'm trying to do some exercises with Human Task Service and ADF, but I have no clue how to do it. Ok here is what I'm trying to do. I've got a small BPMN process, which calls a WebService and gets a list of locations. Afterwards the locations are passed to the user task. A location is composed of the following elements: street (string), city (string) and a zipcode (integer).
The user should be able to select a startLocation, an endLocation and a startDate when he wants to do his trip. The result should be passed to the process.
So far I've created an Human Task with the following parameters: a list of locations, a start location, an end location and a date. I used the autocreation tool to create an adf form. The tool always creates a single table for the locationList and uses input fields for all the elements of startLocation and endLocation. But I want to use 2 selectOneChoice lists, one for startLocation and one for endLocation. An item in the selectOneChoice list should be a single String containing street, city and zipcode.
Could somebody tell me the basic steps to do so? Where and how can I do the transformation of a 'location' into a single string and vice versa? How to bind a selectOneChoice to locationList and startLocation?
Thank you in advance, Chris

You should be able to drag the parameter of the method over to the page and choose to drop it as a selectOneChoice component - you'll then need to bind it to a data control that will provide the possible list of values.
Here is how you would do this conversion of a parameter to a dropdown list in an ADF BC case:
