I've been developing a UI5 app that uses a model to store notifications. I want to display these notifications inside a MessagePopover that can be triggered using the footer.
The data binding works perfectly. I can see that all the properties are set and match the data inside the model. But the link in the details page is not showing up.
When I use a static Link (i.e. a static link to google.com) that is not using data binding, the link is rendered.
Does anyone of you came across the same problem and has a solution for it?
Here is my code:
sap.ui.define([
"sap/ui/core/mvc/Controller"
], function(BaseController) {
return BaseController.extend("test.Test", {
onShowNotificationPopover: function(oEvent){
if (!this._notificationPopover) {
var oMessageTemplate = new sap.m.MessageItem({
type : '{data>type}',
title : '{data>title}',
subtitle : "{data>subtitle}",
description : '{data>description}',
markupDescription : "{data>markupDescription}",
groupName : "{data>groupName}"
});
var oLink = new sap.m.Link({
text : "{data>link/text}",
href : "{data>link/url}",
target : "_blank"
});
/* Working with static */
// oLink = new sap.m.Link({text: "Google", href: "http://google.com", target: "_blank"})
oMessageTemplate.setLink(oLink);
var oPopover = new sap.m.MessagePopover();
oPopover.bindAggregation("items",{
template: oMessageTemplate,
path: "data>/notifications"
});
this._notificationPopover = oPopover;
this.getView().addDependent(this._notificationPopover);
}
this._notificationPopover.toggle(oEvent.getSource());
}
});
});
The view contains the following:
<mvc:View xmlns:mvc="sap.ui.core.mvc" xmlns:f="sap.f" xmlns="sap.m" controllerName="test.Test">
<f:DynamicPage showFooter="true">
<f:footer>
<OverflowToolbar>
<Button icon="sap-icon://message-popup" type="Emphasized"
press="onShowNotificationPopover" />
</OverflowToolbar>
</f:footer>
</f:DynamicPage>
</mvc:View>
And the index.html
<html>
<head>
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta http-equiv='Content-Type' content='text/html;charset=UTF-8'/>
<script src="https://openui5.hana.ondemand.com/resources/sap-ui-core.js"

data-sap-ui-bindingSyntax="complex"
data-sap-ui-resourceroots='{
"test": "."
}'
>
</script>
<script>
sap.ui.getCore().attachInit(function() {
var oModel = new sap.ui.model.json.JSONModel();
oModel.setData({
notifications: [{
type: "Error",
title: "Title1",
subtitle: "Subtitle",
description: "This is a description and below you should see a link",
markupDescription: false,
groupName: "notification",
link: {
text: "Click here",
url: "http://www.google.com"
}
}]
});
var oView = sap.ui.xmlview("test.Test");
oView.setModel(oModel, "data");
oView.placeAt("content");
});
</script>
</head>
<body class="sapUiBody" role="application">
<div id="content"></div>
</body>
</html>
I found a solution for my problem: the event itemPress of MessagePopover.
The event handler inside the controller:
onNotificationItemSelect: function(oEvent){
var oItem = oEvent.getParameter("item"), oBindingContext = oItem.getBindingContext("data");
var oData = oBindingContext.getModel().getProperty(oBindingContext.getPath());
oItem.getLink().setText(oData.link.text);
oItem.getLink().setHref(oData.link.url);
}
And you have to register it:
var oPopover = new sap.m.MessagePopover({
itemSelect: this.onNotificationItemSelect
});
Additional Information
When you display the content of the popover using
console.log(oPopover.getItems()[0].getLink())
the correct properties are shown. see here
But when you search the DOM you can see that the link is copied and does not contain the required binding. see here
