Hey,
I've been going through the process of upgrading my applications/widgets from ExB version 1.10 to 1.12 and noticed that the out-of-the-box List Widget data action isn't working correctly anymore.
I have two different List widgets, Site and Site Updates which have a 1-to-many relationship, so when I click on the "Site" List it will show all the related "Site Updates" in the other list. It worked great in version 1.10 but not in version 1.12 where now the Site Updates list returns 0 records.
Here is action setup I am using:

I would appreciate any help, Thanks!
