[OmniFaces utilities (2.0)] Check if the current faces context is available

[OmniFaces utilities] The hasContext() method returns true when the current faces context is available (i.e. it is not null).

See also: Faces#getContext()

import org.omnifaces.util.Faces;
   // ... there is a FacesContext, so do something

or, you will prefer:

import static org.omnifaces.util.Faces.hasContext;
   // ... there is a FacesContext, so do something

I like this method because is a very nice shortcut for:

FacesContext fc = FacesContext.getCurrentInstance();
if(fc != null){
   // ... there is a FacesContext, so do something
