No, the reason is that it ClickEvent#preventDefault() in a ClickHandler. If you do the same with an Anchor in your ClickHandler, it'll work too. Hyperlink/InlineHyperlink though has some differences with Anchor that make it worth it: - the link's href="" is the history token the Hyperlink targets, so you can right-click -> open in new window (or tab), or ctrl+click or middle-click or whatever to open the link in another window/tab; and you can of course also drag'n'drop the link into another application to have a direct URL to the "page" targeted by the Hyperlink - the ClickHandler only ClickEvent#preventDefault() under some conditions, so that the right-click, middle-click and ctrl+click work OK (and the conditions are different depending on the browser, thanks to GWT's "deferred binding" feature) If you don't want this behavior, then a Button or Label/InlineLabel would be more appropriate than Anchor or Hyperlink/InlineHyperlink.
