Opening Injected Page in a new tab.

Hi,

I have a javascript that trigger a page navigation. It's working perfectly
with the code below.

    @InjectPage
    private AddNode addNodePage;

    @OnEvent("ManageNode")
    @PublishEvent
    Object manageNode(@RequestParameter(value = "param", allowBlank =
false) String param) {
        JSONObject jsonObj = new JSONObject(param);
        long nodeId = jsonObj.getLong("nodeId");
        addNodePage.activate(nodeId);
        return addNodePage;
    }


A new requirement now arrive to open it in a new tab/page instead of
navigating to it. How can i do this from the java code?

Thank you very much.
