[OmniFaces utilities (2.2)] Get the RichFaces PartialViewContext implementation


[OmniFaces utilities] The getRichFacesPartialViewContext() method returns the RichFaces PartialViewContext implementation. RichFaces 4.0-4.3 ExtendedPartialViewContextImpl does not extend from PartialViewContextWrapper. So a hack wherin the exact fully qualified class name needs to be known has to be used to properly extract it from the FacesContext#getPartialViewContext().

Method:
See also: Ajax#getContext()
Usage:

import org.omnifaces.util.Hacks;
import javax.faces.context.PartialViewContext;
...
PartialViewContext pvContext = Hacks.getRichFacesPartialViewContext();
if(pvContext != null){
   // do something
} else {
   // do something else
}
