Set Focus for Primefaces Component in Bean with WidgetVar with RequestContex Execute

Question

Is there a way to set my component focus after an function call to an other component with Primefaces RequestContex?

i tried:

RequestContex.getCurrentIns

Looks like you're under a couple of misconceptions here:

1. That you can execute Java code in RequestContext API.

   RequestContext.getCurrentInstance().execute("(((InputText) event.getComponent()).getWidgetVar()).Focus();");
   

   You can't. The code above will not work. execute is built for JavaScript only.

2. The function name you're looking for is focus(). JS is case-sensitive. So Focus <> focus. So I think what you should have there is

   RequestContext.getCurrentInstance().execute("yourClientSideId.focus();");
   

   Where yourClientSideIdshould correspond to the widgetVar attribute of the component you're interested in. I'm not sure what the PF object you're referencing in your code is supposed to be. I've never seen it. Perhaps you meant the PrimeFaces object?

In the event of failure of the above, you could always use the scrollTo method on RequestContext:

RequestContext.getCurrentInstance().scrollTo("yourComponentWidgetVar");
