No data shows in preview

  

Hello experts,

I'm following lesson Data Queries and Widgets 2 from Developing Outsystems Web Applications.  Figure 18 shows a few records in data preview area in an aggregate (see below).  I've done every step from the beginning (including adding the participants to a movie through the deployed web app) but the same preview shows no record.  I wonder if I've missed anything in the previous steps or any simple 'display data' button. 

 

well, it depends what your filter is...

and/or you have something that deletes everything for example :)


If you view data on the person entity (right click the entity in the data tab, and click the view data option), does any data show in there?
