Primefaces start progressBar from backing bean

Is there any possibility to start progress bar (ajax) component from backing bean? https://www.primefaces.org/showcase/ui/misc/progressBar.xhtml . If yes, how could I do that?

This one is pretty easy. Assume your progress bar looks like this...

<p:progressBar id="progressBarClient" widgetVar="pbClient" />

Just run this in your Java code...

PrimeFaces.current().executeScript("PF('pbClient').start();");

See the Showcase Example for more info.
