Question

I would like to add an URL fragment #top to a HtmlOutcomeTargetLink, but cant figure out how. For an HtmlOutputLink I just use the following:

      HtmlOutputLink link = new HtmlOutputLink();
      String urlWithFragment = url + "#top";
      link.setValue(urlWithFragment);

How to acomplish this for a HtmlOutcomeTargetLink?

Unfortunately the following does not work:

      HtmlOutcomeTargetLink link = new HtmlOutcomeTargetLink();
      String urlWithFragment = context.getViewRoot().getViewId() + "#top";
      link.setOutcome(urlWithFragment);

Thanks for your help!

Answer 1

The outcome of HtmlOutcomeTargetLink (the <h:link>) only takes navigation case outcomes, not URLs. The navigation case outcomes do not support URL fragments. Those needs to be set as a separate fragment attribute.

link.setFragment("top");

Update: wait, there’s no setter for that on the UIOutcomeTarget parent class. I suspect an oversight in the generated code (funnily it’s mentioned here in Mojarra snapshot docs and here in a MyFaces testcase). You should be able to set it directly on the attribute map:

link.getAttributes().put("fragment", "top");
