How can we create custom editor( means editor without any entity) in CUBA ? e. g. Suppose we have a custom screen having few textboxes( which are created in the controller ) and we need to show the user inputs from those boxes in one entity. Also the screen that is created is dynamic means the contents of the screen are decided in run time. we have our own service to deal with that but the only problem occurs is window actions. While adding windows actions it shows the exception to rename the scree id to end with .edit. It is showing IllegalArgumentException: MetaClass not found for TestData/b] exception when modifying the screen name and id in web-screen.xml and web-menu.xml.
Is there any way to create a transaction screen without any entity ?
