RE: Matisse with XML?

I suprises me that no one else see the potential in this feature request? Or has this mailinglist simply fallen asleep?

I don't see that component layout belongs in the application as java statements. As I see it, it would be much cleaner to keep the layout in xml (form) file and instantiate it whenever needed.

As mentioned earlier, it would make it possible to reuse layout and enable non-developers to alter the layout. Even more it would fit very well with patterns like "Presentation model" / "Model View Presenter". I'm aware that patterns can be applied to the view-class created by Matisse, but it would be simpler if the (requested) FormParser would just request components from my application. The components returned to the FormParser could allready be bound to the data object.

Do you disagree?

It may be that the 'FormParser' is allready available, but I haven't been able to locate it in the source/javadocs?!

I think java.beans.XMLEncoder may already do what you
want to do.  It will take a panel or frame and write
it out to XML in it's format and then you can
reinstate it later.  It's a way to long term serialize
beans and swing objects.
