In my attempt to expand a class using SAPUI5 methodology, I created a basic version to test its functionality. However, the predetermined title is not displaying in this particular example:
var app;
sap.m.Page.extend("MyPage", {
title: "hi",
renderer: {}
});
app = new sap.m.App({
pages: new MyPage({
//title: "Hey there!"
})
});
app.placeAt("content");
An illustration of this issue can be found here:
It seems like there was a mistake in your definition. According to the guidelines outlined in this documentation, it is recommended to specify a default value for control metadata in the following manner:
metadata: {
properties: {
"title": {
type: "string",
group: "Data",
defaultValue: "Hi"
}
}
},
For defining a property with a default value, you can use the following method:
sap.m.Page.extend("MyPage", {
metadata : {
properties : {
title : {type : "string", group : "Data", defaultValue : "hi"}
}
},
renderer: {}
});
However, in the page control, the title property is set using its "setTitle" method rather than in the renderer. This means that when a default value is specified, the "setTitle" property is not called. To work around this issue, you can manually call it during initialization.
sap.m.Page.extend("MyPage", {
init: function () {
this.setTitle("hi");
},
renderer: {}
});
Would you consider this to be a suitable solution for your problem?
