I have a requirement where I need to refresh an entity (Say, Workstations) based on plant selected in a ListPicker. Whenever I select a plant in the ListPicker, the workstation entity must return me only those workstations which belong to that plant. I tried creating rule for the same, and updating the query filter but it doesn't update the values when plant is changed. I created initialization action where I am passing the updated plant in the filter, but that is also not updating the workstations in the entityset when I change the plant in the list picker. Could anyone please help me out how to achieve this requirement. Please note that both the list pickers are on the same page.
