Check the Jetty log. Are you getting a 404 on the resource request?
Also, I dunno why you are doing what you are doing with DockPanel, but in
any case it's probably wrong. Every time you add a widget it'll append
"-parent" to each child. So after 3 adds, the 1st child added will have
class-parent-parent-parent.
Also, that's a potential performance problem. Why aren't you setting the
classname explicitly outside of dock panel. Or create a separate class with
a dedicated method that'll properly set the style name as you want once,
after all children have been added.
Or if you want a more automatic approach, something like
private boolean invalidated = false;
void add(Widget w, Constraints c) {
super.add(w, c);
invalidated = true;
DeferredCommand.addCommand(new Command() {
public void execute() {
if (invalidated) {
invalidated = false;
// refresh style names
}
});
}
or even better create 1 timer & schedule it on every addition, thereby
bypassing invalidate & the need to create a deferred command.
