A DESCRIPTION OF THE REQUEST :
There are times when having the editor in a JTree be layed out again when it has been invalidated. An example would be a text field that expands/contracts based on the amount of text in the editor. The current route of having to create this behavior is not obvious. I think a simple property like:
setLayoutEditorOnValidation(boolean layout); would do the trick.

JUSTIFICATION :
It would make things simpler in situations where you have a dynamically resizing editor.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
easy simple clear way to have a dynamically resizing editor
ACTUAL -
editor size appears static

---------- BEGIN SOURCE ----------
Run this test, start editing. See that the editor doesn't resize.
import javax.swing.*;


public class EditingJTree implements Runnable{

    public void run(){
        JTree jtree = new JTree();
        jtree.setEditable(true);
        JFrame jf = new JFrame();
        jf.add(jtree);
        jf.pack();
        jf.setVisible(true);
    }

    public static void main(String ... args){
        SwingUtilities.invokeLater(new EditingJTree());
    }

}
---------- END SOURCE ----------
