hash format error! using routing - sapui5

Question

I have developed an OpenUI5 app ant it works fine!
But every time that I invoke the routing I have this message:
2015-07-15 16:15:45 hash format error! The current Hash: /line/01 -
log
error
onHashChange
detectHashChange
jQuery.event.dispatch
jQuery.event.add.elemData.handle
It is not a blocking problem but it is annoying because it dirty and fills thi debug console..!
To call the router I write:
this.router = sap.ui.core.UIComponent.getRouterFor(this);
this.router.navTo("activities", {
"id_line": '01'
});
and this is the routing file:
routes: [
...
{
pattern: "line/{id_line}",
name: "activities",
target: ["master_search", "detail_activities"]
},
...
],
targets: {
master_search: {
viewName: "UniversalMenu",
viewLevel: 1,
controlAggregation: "masterPages"
}
,
detail_activities: {
viewName: "DetailActivity",
viewLevel: 4
}
...
}
Edit: this is a snippet where I use jQuery.sap.history
jQuery.sap.require("jquery.sap.history");
jQuery.sap.require("sap.m.InstanceManager");
sap.ui.controller("ui5bp.view.App", {
getDefaultPage : function () {
return "Menu";
},
onInit : function () {
var historyDefaultHandler = function (navType) {
if (navType === jQuery.sap.history.NavType.Back) {
//this.navBack(this.getDefaultPage());
} else {
this.navTo(this.getDefaultPage(), null, false);
}
};
var historyPageHandler = function (params, navType) {
if (!params || !params.id) {
jQuery.sap.log.error("invalid parameter: " + params);
} else {
if (navType === jQuery.sap.history.NavType.Back) {
this.navBack(params.id);
} else {
this.navTo(params.id, params.data, false);
}
}
};
jQuery.sap.history({
routes: [{
// This handler is executed when you navigate back to the history state on the path "page"
path : "page",
handler : jQuery.proxy(historyPageHandler, this)
}],
// The default handler is executed when you navigate back to the history state with an empty hash
defaultHandler: jQuery.proxy(historyDefaultHandler, this)
});
// subscribe to event bus
var bus = sap.ui.getCore().getEventBus();
bus.subscribe("nav", "to", this.navHandler, this);
bus.subscribe("nav", "back", this.navHandler, this);
bus.subscribe("nav", "virtual", this.navHandler, this);
},
navHandler: function (channelId, eventId, data) {
if (eventId === "to") {
this.navTo(data.id, data.data, true);
} else if (eventId === "back") {
//**************************************************
// if(data && data.id){
// this.navBack(data.id);
// } else {
// jQuery.sap.history.back();
// }
var app = this.getView().app;
if(data.type==="master"){
app.backMaster();
}else if(data.type==="detail"){
app.backDetail();
}else{alert("back to master o detail?");};
//**************************************************
} else if (eventId === "virtual") {
jQuery.sap.history.addVirtualHistory();
} else {
jQuery.sap.log.error("'nav' event cannot be processed. There's no handler registered for event with id: " + eventId);
}
},
navTo : function (id, data, writeHistory) {
if (id === undefined) {
// invalid parameter
jQuery.sap.log.error("navTo failed due to missing id");
} else {
var app = this.getView().app;
// navigate in the app control
app.to(id, "slide", data);
}
},
/*
navBack : function (id) {
if (!id) {
// invalid parameter
jQuery.sap.log.error("navBack - parameters id must be given");
} else {
// close open popovers
if (sap.m.InstanceManager.hasOpenPopover()) {
sap.m.InstanceManager.closeAllPopovers();
}
// close open dialogs
if (sap.m.InstanceManager.hasOpenDialog()) {
sap.m.InstanceManager.closeAllDialogs();
jQuery.sap.log.info("navBack - closed dialog(s)");
}
// ... and navigate back
var app = this.getView().app;
var currentId = (app.getCurrentPage()) ? app.getCurrentPage().getId() : null;
if (currentId !== id) {
app.backToPage(id);
jQuery.sap.log.info("navBack - back to page: " + id);
}
}
}
*/
});

Answer 1

In Component.js I had 2 rows where I set up custom myNavBack and myNavToWithoutHash functions:
// 3a. monkey patch the router
var oRouter = this.getRouter();
oRouter.myNavBack = ui5bp.MyRouter.myNavBack; //to comment
oRouter.myNavToWithoutHash = ui5bp.MyRouter.myNavToWithoutHash; //to comment
I have started from an example of app skeleton for my app and then I have implemented the routing with the logic suggested from the framework.
This coexistence of two different methods to navigate produced the error in console. Tahnkyou #TimGerlach
After the comment of the two rows errors have vanished.
