Retrieve not working in modeller

Hi,  am using a retrieve action to retrieve a list of objects of an entity. There are no Xpath constraints on the retrieve. i can see that the objects exist because when they are created, i can see on the variables (when i add breakpoints and debug it), that the objects exist. I then retrieve straight after but nothing is retrieved. Any Advice?

Have the objects been committed? If you set a break point on your retrieve, and you inspect the database at that moment, are there actually any objects in your database (you can inspect this in your database management tool (such as PGAdmin for Postgres) or through console → advanced → start built-in database viewer if you use the local Mendix database)?
