Extend from JavaBeans components

[carmen_maven]

Hello:

I have a JavaBean component X that extends from javax.swing.JInternalFrame, and this component contains buttons and panels. I would like to know how can I create a BeanForm component from component X, that contains the same components that has component X. I need that the new BeanForm besides contains the others components can modify them as well in design time. Is this possible?

I saw JavaBeans Objects file types in NetBeans but I'm not sure how to use them...is there any tutorial or sample about this you can recommend?

I can not extends directly from component X because NetBeans says "Error loading component", in the constructor of it I declare:

if(!Beans.isDesignTime()){
initComponents();
}
so this way NetBeans creates the beanForm ok, but it doesn't show the other components that contains the JavaBean.

I'm working with NetBeans 7.0.1.

thanks in advance,
Carmen

Hi,

I found someething here,
http://netbeans-org.1045718.n5.nabble.com/Why-the-controls-in-extended-form-can-not-be-modified-td2913640.html

that says it can't be done, that you can not modify subcomponents from an extended bean form, this link is from year 2007, is it possible that NetBeans has included something for this? I know that exists a Customizer file type for JavaBeans but i tried to used and my NewExtendedForm doesn't show (in Designer pane) the subcomponents that I have in MyBeanForm..

NetBeans says about Customizer: "Creates a Customizer panel for a JavaBeans component. The customizer can then be used during design time in the IDE to configure the bean."

Is a way to accomplish this or the answer is the same of year 2007?

I also found these:
http://wiki.netbeans.org/FaqFormExtendingForms
http://wiki.netbeans.org/FaqFormCustomContainerBean

but the result is negative..

cheers,
Carmen
