In domain model I have 1-* association in two entities (Movie and Review). As shown in the image:
On mendix form, I need to show Movie names in first drop down and corresponding movie reviews in second drop down or as a list. Can anyone help me to achieve this.
To achieve this you will probably need antoher entity, for example 'MovieSelection' which has an association to 'Movie'.
Then you can create a page with this new entity as datasource. You can add a drop-down with movies and you can add a drop-down, datagrid, listview with corresponding reviews through the association review_movie.
