Why is OmniFaces Ajax utility's oncomplete() not working when invoked by preRenderView event?

Question

My preRenderView event invokes OmniFaces Ajax utility's oncomplete() method to execute javascript on the client. I just tested this, and the javascript is not executed on the client.

My f:event is below.

<f:metadata>
    <o:enableRestorableView/>
    <f:event type="javax.faces.event.PreRenderViewEvent" listener="#{pageNavigationController.preRenderView()}"/>
</f:metadata>

My pageNavigationController.preRenderView() is below,

public void preRenderView() {
    if (initLayoutForPage) {
        // initialize layout for page
        layoutController.initializeForPage(page);
        initLayoutForPage = false;
    }
    if (usersController != null) {
        usersController.preRenderView();
    }
}

which calls usersController.preReviewView() below, which invokes Ajax utility's oncomplete().

public void preRenderView() {
        Ajax.oncomplete("document.getElementById('menuBarForm:btnLogout').click();");
}

Currently in production, the javascript above works as designed; this javascript is called as follows.

    <script>window.onbeforeunload = function() { document.getElementById('menuBarForm:btnLogout').click(); }</script>

So, why is the javascript not being executed on the client?

EDIT: I no longer need this functionality as I just figured out a workaround for the original problem, but I would appreciate an answer to this question. Thanks. :)

Answer 1

I just confirmed that Ajax.oncomplete() works as designed even when executed during/via preRenderView event. OmniFaces 'Ajax' utility is for 'Ajax' requests. I was under the assumption that OmniFaces Ajax.oncomplete() would send javascript to client during preRenderView on a FPR (full page refresh or non-AJAX request).
