Mapping of query params for Process Objects doesn't work

Hi all,

I'm about to create some interactions with processes and wanted to propagate options for a Select Box / Combo Box from a process task list. The "Quick Start" -> "Add Option" Wizard runs fine until the last step where I can set query parameters for the service call. The mapper doesn't work (see below). This is quite relevant since I am not able to filter the response to a specific process alias and process instance status. But I'll get a list of all process instances (running and closed and for all process definitions) instead. I tried to add the mapping manually but selecting a different target attribute the editor is stuck.
