Get bound values from pressed List Item in UI5 controller - sapui5

I'm a beginner to SAP Fiori (UI5) and trying to retrieve a value from a table made with sap.m.Table in SAP Web IDE. But I don't succeed. Anybody hints on how to get there?
<Table id="table0" items="{/Entity1_Set}">
<ColumnListItem detailPress=".onShowHello" type="DetailAndActive">
<Text id="text5" maxLines="0" text="{Id}" />
<Text id="text6" maxLines="0" text="{field1}" />
<Text id="text7" maxLines="0" text="{field2}" />
<Text id="text8" maxLines="0" text="Euro"/>
</ColumnListItem>
<columns>
<Column id="column0">
<Label id="label0" text="Floor"/>
</Column>
</columns>
</Table>
sap.ui.define([
"sap/ui/core/mvc/Controller",
"sap/m/MessageToast",
], function(Controller, MessageToast) {
"use strict";
return Controller.extend("QuickStartApplication.controller.View1", {
onShowHello: function(){
MessageToast.show("Hello World!");
},
});
});
In the "hello world"-MessageToast, I would like to display values of the fields in my table.

You can pass parameters in the function, which is called during an event.
Please see also https://sapui5.hana.ondemand.com/#docs/api/symbols/sap.m.ListItemBase.html#event:detailPress
Using these parameters, you can access the bound data.
Please see the following code on how to read the binding context of the ColumnListItem:
detailPress : function(oEventParams){
var oListItem = oEventParams.getSource();
var oBindingContext = oListItem.getBindingContext(); var sSomePropertyValue = oBindingContext.getProperty("<nameOfProperty>"); }
Using .getProperty, you can access your field values.

Missing table template on back and forth navigation

I am trying to build an application that has table#1 with clickable items and display data in another view with table#2 depending on which item you clicked in the first table.
This is some weird behaviour and I'll try to explain the problem the best I can:
The application works fine the first time you use it - I click an Item in table#1 -> it navigates to the view with table#2 and displays the dependent data. Everything works perfectly fine.
Now if i navigate back to table#1 and click another item, it loads table#2 but without any data.
The third time (and every time after that) I navigate back and click an item in table #1 and table#2 is supposed to load I get the error message :
"Error: Missing template or factory function for aggregation items of Element sap.m.Table"
I have tried reloading the item aggregation, destroying the template on navigation, reloading model data and setting the templateSharable flag to true / false but nothing helped in any way.
I'm posting the relevant code for the view with table #2 below
My XML Code:
<f:SimpleForm id="simpleform" editable="true" layout="ResponsiveGridLayout">
<f:content>
<semantic:SemanticPage id="page" headerPinnable="false" toggleHeaderOnTitleClick="false" >
<semantic:content id="posContent">
<Table
id="rkDetailTable"
noDataText="{i18n>tableNoDataText}"
>
<columns>
<Column>
<Text text="Pos ID"/>
</Column>
<Column>
<Text text="{i18n>Art_RkDetail}" />
</Column>
<Column>
<Text text="{i18n>Betrag_RkDetail}"/>
</Column>
</columns>
<items>
<ColumnListItem id="rkDetailTableTemplate" type="Navigation" press="onDetail">
<cells>
<ObjectIdentifier title="{RkposId}" />
<Text text="{RksatzId}" />
<ObjectNumber number="{RkposBetrag}" unit="EUR" />
</cells>
</ColumnListItem>
</items>
</Table>
</semantic:content>
</semantic:SemanticPage>
</f:content>
</f:SimpleForm>
The corresponding controller:
onInit: function () {
this.getRouter().getRoute("RkItemDetail").attachMatched(this.onRouteMatched, this);
},
onRouteMatched: function (oEvent) {
var oArguments = oEvent.getParameter("arguments");
var RkId = oArguments.RkId;
var sBindingPathAbrechnung = "/AbrechnungSet(" + RkId + (")");
this.getView().byId("simpleform").bindElement(sBindingPathAbrechnung);
var sBindingPathPosition = "/AbrechnungSet(" + RkId + (")/ToPos");
this.byId("rkDetailTable").bindItems({
path: sBindingPathPosition,
template: this.byId("rkDetailTableTemplate"),
templateShareable: true
});
}
Disregard the element binding, it is used for something else in that view.
Thank you!
In you table change the <items> aggregation to <dependents>.
<Table
id="rkDetailTable"
noDataText="{i18n>tableNoDataText}"
>
<columns>
...
</columns>
<dependents>
<ColumnListItem id="rkDetailTableTemplate" type="Navigation" press="onDetail">
...
</ColumnListItem>
</dependents>
</Table>

Data Binding from TableSelectDialog to Form

I'm using TableSelectDialog to view some Carrier details. All I need is: If I select any item (row), then all the values from that row should get automatically populated to the form input fields.
In the attached image, if Carrier Name is selected from TableSelectDialog, then the remaining fields should be populated based on that value.
You can achieve the required functionality using the Binding context that you receive from the TableSelcect Dialog.
But for binding context to work properly, both form and the table select dialog should refer to the same Model.
Below is the working code:
VIEW.XML:
Has a Button to trigger the table select dialog.
Has a form.
<l:VerticalLayout class="sapUiContentPadding" width="100%">
<l:content>
<Button class="sapUiSmallMarginBottom" text="Show Table Select Dialog"
press="handleTableSelectDialogPress">
</Button>
<VBox class="sapUiSmallMargin">
<f:SimpleForm id="SimpleFormDisplay354">
<f:content>
<Label text="Supplier Name" />
<Text id="nameText" text="{SupplierName}" />
<Label text="Description" />
<Text text="{Description}" />
<Label text="ProductId" />
<Text text="{ProductId}" />
<Label text="Quantity" />
<Text id="countryText" text="{Quantity}" />
</f:content>
</f:SimpleForm>
</VBox>
</l:content>
</l:VerticalLayout>
Controller:
onInit: function () {
// set explored app's demo model on this sample
var oModel = new JSONModel(jQuery.sap.getModulePath("sap.ui.demo.mock", "/products.json"));
this.getView().setModel(oModel);
},
handleTableSelectDialogPress: function (oEvent) {
if (!this._oDialog) {
this._oDialog = sap.ui.xmlfragment("sap.m.sample.TableSelectDialog.Dialog", this);
}
this.getView().addDependent(this._oDialog);
// toggle compact style
this._oDialog.open();
},
handleClose: function (oEvent) {
var aContexts = oEvent.getParameter("selectedContexts");
if (aContexts && aContexts.length) {
// MessageToast.show("You have chosen " + aContexts.map(function(oContext) { return oContext.getObject().Name; }).join(", "));
this.byId('SimpleFormDisplay354').setBindingContext(aContexts[0]);
}
oEvent.getSource().getBinding("items").filter([]);
}
Now, we also have a Select dialog and on click of any Item we call method : handleClose
In handleClose, we obtain the clicked Item binding context and then tell the form : hey! refer to this context ( which is present in the model). Binding context has a path which tells the form from where to do the relative binding.
Please feel free to contact for more information.

How can I bind a single property of my OData service to a Form?

Will you please tell me how to refer to the first tabular (and single) record?
There is a table with only one record:
<Table items="{WaybillsPlaces}" mode="SingleSelectMaster">
<columns>
<Column hAlign="Center">
<header>
<Text text="Number" />
</header>
</Column>
</columns>
<items>
<ColumnListItem>
<cells>
<Text text="{CoNumber}" />
</cells>
</ColumnListItem>
</items>
</Table>
How can I read the field of the first record without a table?
<Text text="{WaybillsPlaces[0]/>CoNumber}"/>
I get a table reply, but I do not want to display it in the table - I want to display it in the form in text boxes, so there will always be one line in the response.
<entry>
<id>
http://xxxxx.xxx.local:8000/sap/opu/odata/sap/LOGISTICS_SRV/WaybillsPlaces('4610103052')

EDIT (As #Denis description in the comments):
I have an OData giving me the following entry
<entry>
<id>
http://xxxxx.xxx.local:8000/sap/opu/odata/sap/LOGISTICS_SRV/WaybillsPlaces('4610103052')

<d:CoNumber>46101030520001</d:CoNumber>
</m:properties>
</content>
</entry>
How can I bind the CoNumber property with a Input within a From ??
give and ID to your table, get the table in your controller and call its 'getItems()' method. Then get the first object in the returned array:
In your view
<Table id="myTable" items="{WaybillsPlaces}" mode="SingleSelectMaster">
<columns>
<Column hAlign="Center">
<header>
<Text text="Number" />
</header>
</Column>
</columns>
<items>
<ColumnListItem>
<cells>
<Text text="{CoNumber}" />
</cells>
</ColumnListItem>
</items>
</Table>
In your controller
onCertainEvent(evt){
var oTable = this.getView().byId('myTable');
var oFirstItem = oTable.getItems()[0]; // This is your ColumnListItem object in the first row
var oFirstCellItem = oFirstItem.getCells()[0]; // This is your Text object in the first cell of the first row
var sCellText = oFirstCellItem.getText(); // This is the text string in your first cell of the first row
}
EDIT: bind only the first item in your model
In this case you can do aggregation binding. For aggregation binding you need multiplicity greater than 1. So do property binding in yout ColumnListItem with WaybillsPlaces/0/CoNumber
<Table id="myTable" mode="SingleSelectMaster">
<columns>
<Column hAlign="Center">
<header>
<Text text="Number" />
</header>
</Column>
</columns>
<items>
<ColumnListItem>
<cells>
<Text text="{WaybillsPlaces/0/CoNumber}" />
</cells>
</ColumnListItem>
</items>
</Table>

EDIT2: Bind a form input to a certain property in a OData Model
Here I'm gonna use Northwind OData service, for ease of use, but you just need to use your own model. I used the "Customers" entitySet (a.k.a "Customers" DB table), and the "CustomerName" property in this entitySet.
In your case (as per the given OData in the description, you should use the 'WaybillsPlaces' entity and your 'CoNumber' property. If you want to access one specific entry, provide the Key between parenthesis in the binding URL (in your case: WaybillsPlaces('4610103052')).
I highly recommend you to read more about OData binding in UI5 (here and here). In a productive application, please set your OData model in the manifest.json file, to be sure that the $metadata call is done when the application starts, avoiding this way performance and many other issues.

SAPUI5: Refreshing table contents after oData.read

Im building an application with two textboxes, a button and a table. On pressing the button, an array of filters is composed from the contents of the textboxes and sent to my oData service in a read request. Right now, when one record is returned (as it shows in the console), the table will not be updated. What am I missing?
This is the table:
<Table id="PLTab" items="{/ORDSET}">
<headerToolbar>
<Toolbar>
<Title text="Planned Orders" level="H2" />
</Toolbar>
</headerToolbar>
<columns>
<Column>
<Text text="Product" />
</Column>
<Column>
<Text text="Planned Order" />
</Column>
<Column>
<Text text="Production Planner" />
</Column>
</columns>
<items>
<ColumnListItem>
<cells>
<ObjectIdentifier title="{Maktx}" text="{Matnr}" />
<Text text="{Ordno}" />
<Text text="{Name}" />
</cells>
</ColumnListItem>
</items>
</Table>
And this is the relevant part of the controller:
onInit: function() {
var oModel = this.getOwnerComponent().getModel("path");
oModel.refresh(true);
this.getView().setModel(oModel);
},
openOrders: function(oEvent) {
var PLFilters = [];
PLFilters.push(new sap.ui.model.Filter({
path: "Matnr",
operator: sap.ui.model.FilterOperator.EQ,
value1: this.getView().byId("Product").getValue()
}));
PLFilters.push(new sap.ui.model.Filter({
path: "Locno",
operator: sap.ui.model.FilterOperator.EQ,
value1: this.getView().byId("Location").getValue()
}));
var oModel = this.getOwnerComponent().getModel("path");
oModel.read("/ORDSET", {
filters: PLFilters,
success: function(oData, oResponse) {
console.log(oData);
}
});
}
Thanks & regards,
Max
var oModel = this.getOwnerComponent().getModel("path");
You use the model named "path" to read data, but in your XML View you use the default model (unnamed).
Try to change to
var oModel = this.getOwnerComponent().getModel();

Get selected item from sap.m.Select from a sapui5 table column

I am using sap.m.Table, where I have 3 columns, as sap.m.text, sap.m.setect and the last one is button.
My model code
var oModel = new sap.ui.model.odata.OData("url");
sap.ui.getCore().setModel(oModel ,"data");
Table view code(cells)
var oTemplate = new sap.m.ColumnListItem({
cells : [
new sap.m.Text({
text: "{data>Address}"
}),
new sap.m.Select({
id:"sel",
items: {
path: "data>/OPERATORS", // this is a diffent table
template: new sap.ui.core.Item({
text: "{data>firstName} {data>lastName}"
})
},
forceSelection: false
}),
new sap.m.Button({
text : "Start",
press : [oController.onPressStart, oController]
})
]
});
oTable.bindItems("data>/ORDR", oTemplate); //differnt table
Working fine, getting all required data on the specific table.(Notice first column is coming from ORDR table and second one is coming from OPERATORS table).
Now on button click I wanted the specific row data. My code as follows -
onPressStart : function(oEvent){
var obj = oEvent.getSource().getBindingContext("data").getObject();
},
"obj" gives me ORDR table row objects(where I pressed the button).
Now I also want the value I will select on the dropdown box. How to get it.
Please suggest, Thank you
JSbin Link - http://jsbin.com/quhomoloqo/edit?html,console,output
See this working example:
Please note how (for the sake of this question) created two models:
One named 'orig' which holds your original OPERATOR and ODRD data, and
one named 'data' which holds a copy of the OPERATOR data, with an added Address property.
See the view code on how the two models are used (the new one for the table, the old one for populating the dropdown)
sap.ui.controller("view1.initial", {
onInit : function(oEvent) {
},
onAfterRendering : function() {
// your original model
var oModel = new sap.ui.model.json.JSONModel();
var oData = {
"ODRD":[
{"Address":"UK"},
{"Address":"US"}
],
"OPERATORS":[
{"firstName":"a","lastName":"b"},
{"firstName":"c","lastName":"d"}
]
};
oModel.setData(oData);
this.getView().setModel(oModel, "orig");
// the model you actually need
var oNewModel = new sap.ui.model.json.JSONModel();
var oNewData = oData.OPERATORS.map(function(result) {
return {
firstName : result.firstName,
lastName : result.lastName,
keyToAddress : null
}
})
oNewModel.setData({
"OPERATORS" : oNewData
});
this.getView().setModel(oNewModel, "data");
