Custom Components don't show

[jonaumann]

I have a custom AutoComplete-Textfield that inherits from JTextField. If I add it to the container (in the source code), it does not show up in the designer, but it is shown with the correct icon in the component tree.

Any exceptions in your Eclipse ".log" file?

Can you provide a test case?

We have lots of examples of custom JTextFields and they all work fine on our end.

I have sent you the classes, maybe you can find the reason.

If you look in your Eclipse ".log" file, you should see an InstantiationException for each of the widgets indicating that neither could be instantiated.

The basic problem is that these widgets are not valid JavaBeans because they are missing their default constructors.

Add a default constructor to each, and they will both work fine. For example...

Code: Select all

public JAutoTextField() {
    this(new ArrayList());
}
