javascript - How to add a line break to text in UI5?

The escape character and Unicode character u000a will only work in JavaScript. However, I'm trying to add a line break in XML view as below. But doesn't work:

<u:TimelineItem text="First Line
 SecondLine" />
See Question&Answers more detail:os

New lines in text controls can be added with the following characters:

  • In XML views or XML fragments:

    • Line feed: &#10; or &#x0A;.
    • Recommended:* In combination with carriage return: &#13;&#10; or &#x0D;&#x0A;.

  • In JS or i18n.properties files:

    • Line feed: or u000a.

    • Recommended:* In combination with carriage return: or u000du000a.

    • Alternatively, consider using template literals instead of concatenating the above characters manually (i.e. simply replace "..." with `...`).

  • Some UI5 controls allow the HTML tag <br> (in XML: &lt;br>) out of the box:

* See Issues with different newline formats. It is recommended to use the combination with Carriage Return for most of the internet protocols.


Here is a UI5 demo with sap.suite.ui.commons.TimelineItem* and sap.m.Text:

globalThis.onUI5Init = () => sap.ui.require([
  "sap/ui/core/mvc/XMLView",
  "sap/m/Text",
], async (XMLView, Text) => {
  "use strict";
  
  const view = await XMLView.create({
    definition: `<mvc:View xmlns:mvc="sap.ui.core.mvc" height="100%">
      <App xmlns="sap.m" autoFocus="false">
        <Page showHeader="false" class="sapUiResponsiveContentPadding">
          <commons:TimelineItem xmlns:commons="sap.suite.ui.commons"
            text="Multiline supported&#10;in Timeline items (XML)"
          />
          <HBox id="myBox" justifyContent="SpaceAround">
            <Text
              text="This&#10;is&#x0A;a&#13;&#10;text (created in XML view)!"
              renderWhitespace="true"
            />
          </HBox>
        </Page>
      </App>
    </mvc:View>`,
  });
  
  const textCreatedInJS = new Text({
    renderWhitespace: true,
    text: "And this
isu000aanother
text (created in JS)!",
  });
  view.byId("myBox").addItem(textCreatedInJS);
  view.placeAt("content");
});
<script id="sap-ui-bootstrap"
  src="https://ui5.sap.com/resources/sap-ui-core.js"
  data-sap-ui-libs="sap.ui.core,sap.m,sap.suite.ui.commons"
  data-sap-ui-theme="sap_fiori_3"
  data-sap-ui-oninit="onUI5Init"
  data-sap-ui-async="true"
  data-sap-ui-compatversion="edge"
  data-sap-ui-excludejquerycompat="true"
  data-sap-ui-xx-waitfortheme="init"
></script>
<body id="content" class="sapUiBody"></body>
