Is GWT build of Custom tags? Debugging in the java code means debugging the custom tags?

There are no custom tags in GWT, if you are comparing to other approaches.

A simple application that shows two buttons on the screen would have code similar to:

HorizontalPanel hp = new HorizontalPanel();
Button b1 = new Button("OK");
Button b2 = new Button("Cancel");
b1.addClickListener(new ClickListener(){
public void onClick(Widget sender){
Window.alert("You clicked OK");
}
});
hp.add(b1);
hp.add(b2);
RootPanel.get("SomeDOMElement").add(hp);

so you can see from the code there are no custom tags.

What is present here is a reference to a DOM element in the final line - this GWT code will try and place the DOM representation of the HorizontalPanel hp within the SomeDOMElement DOM element on your HTML page.

Another place where there are "tags" is where you wish to communicate to the compiler. So, for example, when you want an object to be serialized you indicate to the compiler in a tag within a comment the underlying object type (this should disappear when moving away from Java 1.4 syntax).

But as for custom tags within your HTML page; there are none.

Hope that answers the question!
