Of course :)
If you just make sure the prefix ("slot") is unique, and the slots are
generated sequentially with no gaps; this would do:
int i = 0;
RootPanel p;
while ((p = RootPanel.get("slot" + i)) != null) {
doSomethingWith(p);
}
Though, if your example is as simple as just being buttons, this:
int i = 0;
Element e;
while ((e = Document.get().getElementById("deleteButton" + i)) !=
null) {
Button b = Button.wrap(e);
doSomethingWith(b);
}
Would save you from creating all the rootpanels, if the server has
generated the buttons already.
