Prior to updating to 16.3, the parameter and return value types displayed just the class name in the class diagram, not the fully qualified namespace and class. I cannot find a way to turn off the fully qualified name.
For example this: +getSomething(request : Request) : JsonResponse
now renders as: +getSomething(request : Design Model.Classes.Symfony.Component.HttpFoundation.Request) : Design Model.Classes.Symfony.Component.HttpFoundation.JsonResponse
making it pretty much impossible/useless/confusing to display the signature on the diagram.
Thank you for your post. As I know, no change has been made in version 16.3 regarding the way to display class members. We will take a look at your case shortly. Meanwhile, please try:
Right-click on the diagram and select Presentation Options > Configure Class Presentation Options from the popup menu.
