I am working with Bonita BPM 7.1, starting to build multi-page forms. It looks like the database connector functionality provides what I need in terms of querying an external database. However, I need to access the connector dynamically within the page. For example, first page-> Select person last Name, second page -> display list of matching people with selection. So between these steps I need to execute a parameterized query to the database. I can build a connector-in, but it always runs before the form.
