Hello All,   NPE - Non Persistent Entity   We have built an APP which has Phone web profile. We have a button on the Home Page - Unload Vehicles. On clicking we are performing below activities:   1) We call a microflow where fetch a list of Objects from Database of the Entity Type TruckLotDetails. 2) We create an NPE object - PageContext and associate the list of above objects using a * - * Association (reference set). We then open a second page by passing PageCOntext NPE as the Data View Entity 3) We are doing this way because in the next page we have a Data View. Inside the data View we have a List View which fetches the Associated Objects and displays them.     Normally earlier, it used to display the lsit of objects as below.   Now the issue is in the main microflow where we are setting the List of Truck Objects on the NPE using the *-* Association, it is throwing an error "Reference value should be of the Type TruckLotDetails" at the Chang Object activity.     But I am associating a List of TruckLotDetails Object only. And I have not made any recent changes to this activity or Microflow. It was working perfectly fine and after some time, it is giving this error when i click the Unload Vehicles Button.     I have tried renaming the association, removing and adding a similar *-* new association. Refreshing the Data Model in Reflection Admin Page, Restarting the Database (although this has no effect on DB since this is an association with NPE)   I have tried updating Security Access rules for the Entity.   I have even tried deploying a previous revision MDA file which was working perfectly fine before my changes in a new and different functionality. But still facing the issue   Attaching Images for the error, the full stack trace logs and microflow screenshot of the change object where i am associating the exact Entity List of TruckLotDetails.   The wierd issue is this is not happening in my local machine. I have also tested by running the App locally in Mendix Studio Pro inside my Application server.   It is only happening when the App is deployed inside the Mendix Service Console    Full Stack trace is below com.mendix.modules.microflowengine.MicroflowException: requirement failed: Reference values should be of type 'MainModule.TruckLotDetails' at MobileSpecific.Act_OpenTrucksForUnload (Change : 'Change 'NewPageContext' (PageContext_TruckLotDetails_FullList)') Advanced stacktrace: at com.mendix.modules.microflowengine.MicroflowUtil.processException(MicroflowUtil.java:83) Caused by:
