Unable load Full Page view when I change any dropdown value from the action area in constellation
I wanted to display the primary fields of a work object based on the customer selected in a dropdown on the action area. I tried couple of ways like calling datatransform, referring data page with reference data pattern etc., no use.

In Pega Constellation, if your full page isn’t updating when a dropdown value changes, it's likely because the UI isn't set to react to the change. To fix this, first make sure your dropdown posts the value when changed (check the "Post value" option). Then, set up a reference data page like D_CustomerDetails[Param.CustomerID] and pass the selected value as a parameter. If you're expecting the UI to refresh automatically but it's not, you’ll need to add a client event on dropdown change, run a data transform to update the data and then trigger a section refresh. Also, make sure the section you're updating is built to react to the data change, or else nothing will show up even if the data updates behind the scenes. This setup lets your page react to user choices without reloading everything manually
