I have found out that if I get sometimes a white screen, but I dont know why. Everytime when I disconnect the blocks of the method screen opens and connect then again the white screen disappear. Why does this happen? Is there a fail connection between the database and the programm?
White screen most often occurs when trying to retrieve non-existent object, an infinite loop and other errors in the algorithms. For this reason, when debugging the application I do not recommend to put the code in screen units Screen.Starts or Screen.Opens. Place check the blocks in a processing unit of a click event on a button.Click. In this case, you’ll know that the error is in the block you click.
