[jdom-interest] isRootElement issue

[Kesav Kumar]

What is actual meaning of isRootElement? is it just to verify whether the
element is attached to document or does it have any parent or not?

I have test case like this.

I created an Element like
Element root = new Element("Root");
Element child = new Element("Child");
root.addContent(child);

Since root and child doesn't have document associate with them both
child.isRootElement() and root.isRootElement() return false.  

Ideally I feel root.isRootElement should return true sice it has a child.

I propose that we should check for getParent == null for determinig the root
or not.

isRootElement returns true only if "document != null".  In other words,
only if it directly holds a reference to its document which only the
root will do.  What's wrong with that?  If you have an actual test case
that fails, please send it, making sure of course to test against the
latest first.  :-)
