Siteorigin with gravity form populated dropdown

Hi,

We’re building a custom widget where we’d like to have a gravity form displayed with a pre_rendered form that gets a dropdown option populated from the widget instance data.

Our variable data gets passed to the widget template just fine see snippet http://pastebin.com/KJchaaQ9

Then in the widget template file I have the add_filter(‘gform_pre_render’,’xxx’), but the values aren’t getting passed to this filter see snippet http://pastebin.com/1bKkZWkp

Please, any assistance would be greatly appreciated.
