MonkeyPatching: PrimeFaces widgets extend/override

Question

I\'m currently using (it\'s working fine)

PrimeFaces.widget.OverlayPanel.prototype._old_init = PrimeFaces.widget.OverlayPanel.prototype.init;
PrimeFaces.widg

I had the same problem, but you're solution was not 100% efficient to my problem (See here https://github.com/primefaces/primefaces/issues/1928)) since you're willing to call _super() from OverlayPanel, and I'm trying to avoid it (it does few things I did not want to). So what I did is this:

/* Quick fix so layout might be handled in dialog component PF #1928 */
if(PrimeFaces.widget.Layout) {
    PrimeFaces.widget.Layout.prototype.init = function(cfg) {
        // skip calling PrimeFaces.widget.Layout.init() on purpose
        PrimeFaces.widget.DeferredWidget.prototype.init.call(this, cfg);

        this.cfg = cfg;
        this.id = this.cfg.id;
        this.jqId = PrimeFaces.escapeClientId(this.id);

        if(this.cfg.full) {          //full
            var dialog = $(this.cfg.center.paneSelector).parents('.ui-dialog-content');
            if(dialog) {             // full + dialog
                this.jq = dialog;
            } else {
                this.jq = $('body');
            }
        } else if(this.cfg.parent) { //nested
            this.jq = $(PrimeFaces.escapeClientId(this.cfg.parent));
        } else {                     //element
            this.jq = $(this.jqId);
        }

        this.renderDeferred();
    }
}

That way init() is completely overrided. I hope it will help few folks out there in this atypical case ;)
