JSF: calling javascript code from Managed Bean not working when forcing page reload

Question

I need to execute a JavaScript code from a JSF Managed Bean's method that is basically to click a button on a facelet (.xhtml file). All this works perfectly by using PrimeFaces' RequestContext.execute("{js here}"), however it no longer works when adding some 'page reload' code lines by using ExternalContext... (please see code below). It seems like the 'page reload' lines prevented the JavaScript code from executing. Any hints is welcome !

public void myMethod() throws IllegalStateException, Exception {

    RequestContext rc = RequestContext.getCurrentInstance();.           

    rc.execute("$('#myButton').click();");

    try {
        ExternalContext ec = FacesContext.getCurrentInstance().getExternalContext();
        ec.redirect(((HttpServletRequest) ec.getRequest()).getRequestURI());

    } catch (IOException e) {
        log.error("Error", e);
    }

RequestContext is for the current request, a redirect is a another request. it can't work.

Try to do something like this:

RequestContext rc = RequestContext.getCurrentInstance();
rc.execute("$('#myButton').click(); window.location = newURL;");

Hi Rostislav, thanks for your hint ! just a question: since I need to reload the same page, shouldn't I use window.location.reload(true) ?

I think that you have a method call is triggered by click some button, so try to turn of AJAX and page will reload automatically. For primefaces buttons use ajax="false" attribute.
