Errors about this.path(...).trigger not being a function...

[IngwiePhoenix]

So I am trying to set up Grapnel for good now. Thign is, I think I am doing something wrong.

This script:

// Commons
import "./Support/Common";

// Modules
import Grapnel from "grapnel";
import oo from "o.o";
import Compatibility from "BIRD3/Support/Compatibility";
import Routes from "./Support/Routes";

var pushRouter = new Grapnel({
    pushState: true,
    root: "/"
});
var hashRouter = new Grapnel({
    pushState: false,
    hashbang: true
});

// Hacky way to enable hashbang AND pushState routing.
var app = pushRouter;
app.get = function(){
    hashRouter.get.apply(hashRouter, arguments);
    Grapnel.prototype.get.apply(this, arguments);
}

oo("[data-pjax]").click(function(e){
    if(hasPushState) {
        // This is a PJAX link. So hold it right there.
        e.preventDefault();
        app.navigate(oo(e.target).attr("href"));
    }
});

Compatibility(function(err){
    if(err) { console.log(err); }
    console.log("Loading routes...");
    Routes(app);
});

app.on("navigate",function(){
    console.log(arguments);
    console.log("Navigating...");
})

app.navigate();

fails:

Uncaught TypeError: this.path(...).trigger is not a function(…)

And I realized, there is no hint in the readme, about how I can let Grapnel trigger the first navigation.

The Routes function is just assigning app.gets. So there is nothing special in there.
