Routing with Parameters - patternMatched Event Not Fired - sapui5

Question

I am working on UI5 application using Web IDE and I have created a view where I need to bind the data based on parameter received from last view. But the patternMatched event is not firing.
manifest.json
"routing": {
"config": {
"routerClass": "sap.m.routing.Router",
"viewType": "XML",
"viewPath": "oomsdisplay.pso.com.view",
"controlId": "app",
"controlAggregation": "pages",
"bypassed": {
"target": ["notFound"]
},
"async": true
},
"routes": [{
"pattern": "",
"name": "worklist",
"target": ["worklist"]
}, {
"pattern": "ZISOHSet/{objectId}",
"name": "object",
"target": ["object"]
}, {
"pattern": "ZISOHSet/{objectId}",
"name": "payobject",
"target": ["payobject"]
}],
"targets": {
"worklist": {
"viewName": "Worklist",
"viewId": "worklist",
"viewLevel": 1
},
"object": {
"viewName": "Object",
"viewId": "object",
"viewLevel": 2
},
"objectNotFound": {
"viewName": "ObjectNotFound",
"viewId": "objectNotFound"
},
"notFound": {
"viewName": "NotFound",
"viewId": "notFound"
},
"payobject": {
"viewName": "PayObject",
"viewId": "payobject",
"viewLevel": 2
}
}
}
Component.js
init: function() {
UIComponent.prototype.init.apply(this, arguments);
// ...
this.getRouter().initialize(); // create the views based on the url/hash
},
Now, I have created a view. When I press the button on view, my second view i.e. PayObject will be called. Here is my code on button press of view one:
fViewPayment: function(oEvent) {
this.getRouter().getTargets().display("payobject", {
objectId: "MyParameterhere"
});
},
Now, here is my PayObejct view's init handler with object matched handler. But it is not working.
onInit: function() {
// ...
var oRouter = sap.ui.core.UIComponent.getRouterFor(this);
oRouter.getRoute("payobject").attachPatternMatched(this._onObjectMatched, this);
},
_onObjectMatched: function(oEvent) { // this event handler is not firing
var sObjectId = oEvent.getParameter("arguments").objectId;
sap.m.MessageBox.show(sObjectId);
// ...
},

Answer 1

If you have two routes with the same pattern, only the first one will be matched in the Router.
{
"pattern": "ZISOHSet/{objectId}",
"name": "object",
"target": ["object"]
}, {
"pattern": "ZISOHSet/{objectId}",
"name": "payobject",
"target": ["payobject"]
}
So in this case "object" will me matched. Change the patter of one of your routes and try again.
Furthermore, use navTo() when navigating:
this.getRouter().navTo("payobject", {
objectId: "MyParameterhere"
});

Answer 2

Instead of using
getTargets().display
Use method navTo from your Router object

Answer 3

You have to routes with identical patterns: "object" and "payobject", I would try to remove one and check again.
