Sometimes in an aggregation binding, I need to add some controls to the generated list of items statically. Is there some elegant solution for this?
Let's say I have a Select with the following code:
<Select width="100%"
items="{project>/Milestones}"
selectedKey="0"
>
<core:Item
key="{project>Id}"
text="{project>Name}"
/>
</Select>
Bound to a model with these data:
{
Milestones: [
{
"Id": 1,
"Name": "Cost Estimation 1",
"Description": "Initial cost estimation"
},
{
"Id": 2,
"Name": "Pid Packages",
"Description": "Ready for RFQs"
},
...
]
}
I want to add an item to the Select with key="0" and value="< Blank >" and have that stay there even when the content of project>/Milestones is changed, but I don't want to add it to the actual aggregation.
The solutions that I have at the moment seem really hackish and create problems later on: creating a new model (property) leads to having the data duplicated in multiple lists and therefor it will probably get out of sync at some point. I've also tried adding the static items through binding events, but this is somewhat error prone and very verbose.
Ok here the promised snippet. First of all, if you just want to add a "blank" item, I recommend you to use ComboBox instead of Select, because you can always delete your selection. I added it to the snippet as well.
But if you want to add an item, you just need to use the addItem() function described here
I also added a button to modify your model, so you can see how the '< Blank >' item remains there even when you change it.

I have a component in SAPUI5 where I need to listen to changes in the binding (Binding.change event). At the moment I'm adding a listener to the Binding in modelContextChange like this:
function onModelContextChange(oEvent){
var oSelect = oEvent.getSource();
var binding = oSelect.getBinding("items");
if(binding){
binding.attachChange(onDataChange, oSelect);
}
}
However this causes all kinds of weird problems, because modelContextChange could be fired multiple times. It would be better to to this in the XML view. I've tried code like this, but it doesn't work.
<Select items="{ path: 'project>/data/', change:'onDataChange' templateShareable: false">
<core:Item key="{project>Id}" text="{project>Parameter}"/>
</Select>
Any recommendations how to do this?
I just came across the problem, too. I solved it in that way:
<Select items="{
path: 'project>/data',
events: {
change: '.onDataChange'
},
templateShareable: false
}">
You can pass an events object to the binding and use the available bindings (e.g. v2.ODataListBinding). Note that you have to use a dot before your function name (.onDataChange). In your controller you can add the function:
onDataChange: function(oEvent) {
// Your implementation...
},
If I remember well from the JS Views, I think it is like this:
<Select items="{ path: 'project>/data/', events: {change:'onDataChange'}, templateShareable: false}">
This is for listening to the Model "change" events.
If you want to listen to the "change" event in the Select control, this is when the user selects a different value in the dropdown, it is like this:
<Select items="{ path: 'project>/data/', templateShareable: false}" change="onDataChange">
EDIT:
Using "modelContextChange" event.
<Select items="{ path: 'project>/data/', templateShareable: false}" modelContextChange="onDataChange">

Note: the change attribute in your XML is incorrect
I managed to get the binding change event with this set to the element that I needed by attaching a modelContextChange to the element and handling attaching the change event to the binding in there. Here's the code from the view controller:
modelContextChange: function(oEvent) {
var oElement = oEvent.getSource();
var binding = oElement.getBinding("items");
if (binding) {
//Binding change event could already be attached, detach it first, if it's there
binding.detachChange(this.onBindingChange, oSelect);
binding.attachChange(this.onBindingChange, oSelect);
// Beacause I used this inside a sap.ui.table.Treetable,
// in some cases binding changes occur without the binding change event firing.
// Manually fire the binding change just in case
// YMMV
binding.refresh(true);
}
},
onBindingChange: function() {
//The code that needs to run at binding change
//"this" is set to the correct element
//I specifically needed to add one element in front of other items in a sap.m.Select
var items = this.removeAllItems();
this.addItem(new sap.ui.core.Item({
key: 0,
text: "< Inherit >"
}));
items.forEach(function(item) {
this.addItem(item);
}, this);
}
I have to create a table (sap.m.Table) in SAPUI5 where rows can be deleted, reordered, and clicked on to open a dialog. So far I've figured out that I can set the Table to mode="delete" and ColumnListItem to type="Navigation" to achieve deleting rows and clicking on rows to open dialogs at the same time:
Is it possible to add the functions to reorder rows to this?
You can use a "editModeEnabled" variable in your view model to change the Table mode to "SingleSelectLeft" and show/hide some buttons. Then in "editMode", use some buttons to insert and remove the items of the table wherever you want

Hi i have a searchfield with this code behind it:
onSearch : function (oEvent) {
if (oEvent.getParameters().refreshButtonPressed) {
// Search field's 'refresh' button has been pressed.
// This is visible if you select any master list item.
// In this case no new search is triggered, we only
// refresh the list binding.
this.onRefresh();
} else {
var andFilter = [];
var sQuery = oEvent.getParameter("query");
if (sQuery && sQuery.length > 0) {
// add filters
var oTableSearchState = [];
oTableSearchState = [new Filter("Supplier", FilterOperator.Contains, sQuery), new Filter("BusArea", FilterOperator.Contains, sQuery), new Filter("CostCenter", FilterOperator.Contains, sQuery),
new Filter("FuncArea", FilterOperator.Contains, sQuery)];
andFilter.push(new Filter(oTableSearchState, false));
}
this._applySearch(andFilter);
}
},
And a filter button that should add aditional filters. Something like this:
onSetFilter : function(oEvent) {
var andFilter = [];
andFilter.push(new Filter("BusArea", FilterOperator.EQ, "5000"));
this._applySearch(andFilter);
},
But of course the "BusArea" part should be dependent on what filters are selected. It could be more than 1 filter. the _applySearch function looks like this:
_applySearch: function(andFilter) {
var oViewModel = this.getModel("worklistView");
this._oTable.getBinding("items").filter(andFilter, true);
// changes the noDataText of the list in case there are no filter results
if (andFilter.length !== 0) {
oViewModel.setProperty("/tableNoDataText",
this.getResourceBundle().getText("worklistNoDataWithSearchText"));
}
}
the problem is that when i add a filter via the filter button, the filters from the searchbar disappear and the other way arround. how can i change my code so that i can add the filters without removing the existing ones?
One solution is to get the Filters from the binding info and push back together with the new Filter using and.
this._oTable.getBindingInfo("items").filters.aFilters;
After our conversation on the chat, I have made this snippet using a global model.
https://jsbin.com/pewavuhonu/edit?html,output
The ComboBox and the Button simulates your Dialog.
The input simulates the SearchField
Both are binded against the global "filtersModel", and both call the _calculateFilters() function when submiting the info

but i can not access to it from code
this.getView().getModel().getProperty('/myOneSet')
or
this.getView().getModel().getProperty('/myOneSet/>param')
not work. How it accessible?
If mainService is an OData service, then your model is an ODataModel. You can access data via methods described in the API, e.g.: read()
this.getView().getModel().read('/myOneSet', {
success: function(oData, response) {
// do sg. with oData
}
});
Most of its data access methods has a second parameter-object with a success function callback. This function will be called asynchronously with the data on the given path upon successful data retrieval from the datasource. Most of the ODataModel API methods works with callbacks. You can read more about callbacks here.
If you defined model in the manifest.json file then you can access it via Component. If you created your project via template then you have a BaseController.js file which is the ancestor of your other controllers and there is a function getComponentModel. So, I would suggest you to try this code in your controller:
this.getComponentModel().getProperty('/myOneSet')
Because of the property name that you try to access I assume you are using an ODataModel. Is that correct?
If that's true you have to consider a few things... ODataModel.getProperty() does not trigger requests. Instead it will return whats already available. If you want to trigger a request you should execute an ODataModel.read(). If you want to get the loaded data from the ODataModel then you should also know when the data has been loaded. This you can achieve by attaching a change event handler when you do the binding.
Instead of describing how to access the data of an ODataModel I wrote s little jsbin example for you (or see below). Just check the change event handler. There are multiple ways to access the data.

so Project->webcontent->View->app.xml
Error is

However, if I program in a different way, it works. Please check the code below:
<mvc:View
xmlns:mvc="sap.ui.core.mvc" xmlns="sap.m"
controllerName="view.app">
<Text text="Hello World"/>
</mvc:View>
In index file
<script>
sap.ui.localResources("view.app");
var app = new sap.m.App({
initialPage:"idmain1"
});
var page = sap.ui.view({
id: "idmain1",
viewName: "view.app",
type: sap.ui.core.mvc.ViewType.XML
});
app.addPage(page);
app.placeAt("content");
</script>
I think the issue looking at your description is the folder where the views are placed are named as View
so Project->webcontent->View->app.xml
Code is
sap.ui.localResources("view.App");
sap.ui.getCore().attachInit(function () {
new sap.ui.xmlview({
viewName: "view.App"
}).placeAt("content");
});
So 3 issues
Folder name is View ====> code is called as view(case sensitive).
View is called app.xml =====> Code is invoked as App(case
sensitive again)
The views are generally called app.view.xml but
you structure says as app.xml need to check this as well.
By fixing these the app should render.
Please check View path in manifest.json ,When creating XML view function has created like this
"routing": {
"config": {
"routerClass": "sap.m.routing.Router",
"viewType": "XML",
"async": true,
"viewPath": "First.UI5.view",
"controlAggregation": "pages",
"controlId": "idAppControl",
"clearControlAggregation": false
},
For Example View name is FirstView, we want add viewname in viewpath
"viewPath": "First.UI5.view.FirstView".
