Happily not so. I finally figured out the cast() voodoo method, which
"converts" the dom.client.Element
instance to a user.client.Element instance. So you can work with
dom.client.Element when possible, then simply
cast() them to user.client.Element when they need to be sent to the
DOM class.
And while I do prefer that getChild, getChildCount, and getChildIndex
methods be implemented in the Node class for convenience,
I was easily able to write my own equivalent methods elsewhere. Here
is an example, where the parameters are dom.client.Element types:
public static int getChildCount(Element elem) {
return DOM.getChildCount((com.google.gwt.user.client.Element)
elem.cast());
}
