fields not showing in detail view of Master-Detail UI5 app

[mkoch_wu]

I am currently creating a Master-Detail UI5 app. I started my design process in Build, then generated a UI5 prototype. Once the prototype was agreed, I actually went back to the drawing board (from a coding perspective) and used one of the master-detail templates to generate a 'leaner' version than the generated one I got out of Build.

I am now in the process of connecting this 'leaner UI5 app with my real-world backend Gateway services.

I basically have a GW service to display open service orders (Order No, Order Description and Order creation date) in the master view list. This part works fine now. Upon selecting a item in this list, I am expecting Order Number and Text to be populated in the detail view. This is the step that's currently not working and I think there is something wrong in my routing/navigation and/or my OData model.

The error message I am getting is: error-chrome.jpeg

Below are my routing and target definitions from manifest.json. I have excluded any of the Error and NotFound views, by the way:

"routing": {
	"config": {
		"routerClass": "sap.m.routing.Router",
		"viewType": "XML",
		"viewPath": "sap.ui.demo.masterdetail.view",
		"controlId": "idAppControl",
		"controlAggregation": "detailPages",
		"bypassed": {
			"target": [
				"master",
				"notFound"
			]
		},
		"async": true
	},
	"routes": [
		{
			"pattern": "",
			"name": "master",
			"target": [
				"detail",
				"master"
			]
		},
		{
			"pattern": "ServiceOrderSet/{Aufnr}",
			"name": "detail",
			"target": [
				"master",
				"detail"
			]
		}
	],
	"targets": {
		"master": {
			"viewName": "Master",
			"viewLevel": 1,
			"viewId": "master",
			"controlAggregation": "masterPages"
		        }
	        }
         }
},

Service metadata. As you can see, I did not create any navigation, as I am not selecting any additional data, like service order operation data, for example:

<EntityType Name="ServiceOrders" sap:content-version="1">
<Key>
      <PropertyRef Name="Aufnr"/>
</Key>

<Property Name="Aufnr" Type="Edm.String" Nullable="false" MaxLength="12" sap:unicode="false" sap:label="Order" sap:creatable="false" sap:updatable="false" sap:sortable="false" sap:filterable="false"/>

<Property Name="Ernam" Type="Edm.String" Nullable="false" MaxLength="12" sap:unicode="false" sap:label="Entered by" sap:creatable="false" sap:updatable="false" sap:sortable="false" sap:filterable="false"/>

<Property Name="Auart" Type="Edm.String" Nullable="false" MaxLength="4" sap:unicode="false" sap:label="Order Type" sap:creatable="false" sap:updatable="false" sap:sortable="false" sap:filterable="false"/>

<Property Name="Erdat" Type="Edm.DateTime" Nullable="false" Precision="7" sap:unicode="false" sap:label="Created on" sap:creatable="false" sap:updatable="false" sap:sortable="false" sap:filterable="false"/>

<Property Name="Ktext" Type="Edm.String" Nullable="false" MaxLength="20" sap:unicode="false" sap:label="Name" sap:creatable="false" sap:updatable="false" sap:sortable="false" sap:filterable="false"/>
</EntityType>

<EntityContainer Name="ZGW_SERVICEORDER_SRV_03_Entities" m:IsDefaultEntityContainer="true" sap:supported-formats="atom json xlsx">

<EntitySet Name="ServiceOrders" EntityType="ZGW_SERVICEORDER_SRV_03.ServiceOrders" sap:creatable="false" sap:updatable="false" sap:deletable="false" sap:pageable="false" sap:content-version="1"/>
</EntityContainer>

In my Master.controller.js, I am getting the listItem parameter. I've checked this in debug and it appears to work.

onSelectionChange: function(oEvent) {
	this._showDetail(oEvent.getParameter("listItem") || oEvent.getSource());
},

and finally the XML coding from my Master view. Also note the Aufnr and Ktext fields, which I would like to display here, but which are currently not showing:

<List id="list" items="{ path: '/ServiceOrderSet', sorter: { path: 'Aufnr', descending: false }, groupHeaderFactory: '.createGroupHeader' }"
busyIndicatorDelay="{masterView>/delay}" noDataText="{masterView>/noDataText}"
mode="{= ${device>/system/phone} ? 'None' : 'SingleSelectMaster'}" growing="true" growingScrollToLoad="true"
updateFinished="onUpdateFinished" selectionChange="onSelectionChange">
<infoToolbar>
<Toolbar active="true" id="filterBar" visible="{masterView>/isFilterBarVisible}" press="onOpenViewSettings">
<Title id="filterBarLabel" text="{masterView>/filterBarLabel}"/>
</Toolbar>
</infoToolbar>
<items>
<ObjectListItem type="{= ${device>/system/phone} ? 'Active' : 'Inactive'}" press="onSelectionChange" title="{Ktext}"
number="{path: 'Aufnr'}">
<attributes>
<ObjectAttribute
text="{path: 'Erdat', type: 'sap.ui.model.odata.type.DateTime', formatOptions: { style: 'short' }, constraints: { isDateOnly: true, displayFormat: 'Date' } }"/>
</attributes>
</ObjectListItem>
</items>
</List>

Update: below is the code of my _showDetail method:

_showDetail: function(oItem) {
	var bReplace = !Device.system.phone;
	this.getRouter().navTo("detail", {
	objectId: oItem.getBindingContext().getProperty("Aufnr")
	}, bReplace);
},

Update: below is the relevant part of my Deatil.xml view

...
<semantic:content>
     <ObjectHeader id="objectHeader" title="{Ktext}" number="{Aufnr}"></ObjectHeader>
...

Does anybody have any pointers where I am going wrong here?

Thanks in advance,

Michael

Can you also please share what the URL looks like (especially the hashpath part) when you get this error?

[mkoch_wu]

There is none with hashpath as far as I can see.

Also, in the UI5 Diagnostics I can see that the bindings in my Detail view are shown as "invalid" ("Ktext invalid").

I've also added the relevant part of my XML view above.

Hi Michael,

Could you please post the code of function _showDetail?

It seems you have not passed Aufnr as parameter when navigating to detail page.

Thanks, Tri.

I have added the _showDetail method at the bottom of my original post.

Hi Michael,

Please try this:

Replace this line in _showDetail

objectId: oItem.getBindingContext().getProperty("Aufnr")

with

Aufnr: oItem.getBindingContext().getProperty("Aufnr")

since the pattern in manifest is using Aufnr

{"pattern": "ServiceOrderSet/{Aufnr}","name": "detail","target": ["master","detail"]}
Also, how do you implement onRouteMatch or bindView in Detail controller?
