I populated the list (children) in the controller class with test data. Each new child object was initialized and added to the Category.Children list. The compiler threw an exception. After some debugger stepping I found that the list was not initialized and was null.

I posted my fix but it shows as being moderated. Here is what I did:

public Category() {
ObservableList<topic> oList = FXCollections.observableArrayList( children );
this.children = new SimpleListProperty<topic>( oList );
}

Thanks for the help!

I read about Beans and I quote: "A no-arg constructor should be
there in a bean.".

The application allows a user to create a file and name it anything they wish.

What happens if the user tries to open an SQlite database from disk that does not contain the created tables?

First of all, sorry if I offended you/him. Secondly, that question was posted eight years ago and I don't even remember what I was working on at the time. Thirdly, I don't even code in C++ anymore.

Please have a nice day. :)

The Class Wizard is the built in wizard form in the VS IDE for creating new classes. It is available from the menus and in the Solution Explorer view. There is no code to post here because the wizard returned that error message and therefore did not create the class code in the editor. I was not confused about anything other than why I could not create the derived class in the first place. This issue has nothing to do with my code, but with the wizard. The error message is to ambiguous for me to resolve the issue.

I thought I was clear on this in my first post: "Is it possible to derive a new class from ListView base class? The class wizard seems to object: "The class cannot be derived from a managed class."."

I don't understand the confusion. The message was copied exactly from the error dialog box. The error was a standard error message generated from the class wizard. I attempted to derived a new custom class with System::Windows::Forms::ListView as the base class. There is also no code for me to post because I never was able to generate a new class.

If I hard code your suggestion I am able to create the class, but not with the class wizard.
