Creating an API connector to pull web data

Using Bonitasoft 7 community edition. Using Yahoo yql, to get a Yahoo finance API.

I have created API calls in forms to get data from Yahoo.However I need to create a call for the same information within the process.

This seemed like viable option however I have been unable to get it to integrate with Bonita 7

I have been getting the error,

MYSQL DB - Select list

I'm trying to get the values from a mysql DB into a select list as possible values. I have created a connector to the database that works. I store the results in a process variable java object = java.util.list called hrcAfdelingen

Now i want to use this list as possible values in my form but i don't know how to get these values. I have tried just putting hrcAfdelingen in the possible values, but that didn't work.

Any suggestions ?
