Call default renderer in custom control

Hi there,

I'm trying to extend the sap.ui.commons.TextView.

I'm wondering if it's possible to call the default renderer first and then make some custom changes.

Here's a little code snippet to make clear what I want to do:

// Extend TextView
sap.ui.commons.TextView.extend("my.TextView", {
    init: function() {
    renderer: {
        render : function(oRenderManager, oControl) {
            // 1. Call the default parent renderer of the Textview
            // 2. Add some custom css or whatever...

Somebody has a an idea if this is possible?

I've read through the guide here :SAPUI5 SDK - Demo Kit

But there I can only find an example how to override the original renderer, but not how to extend it...

    The renderer functions are static you can call sap.ui.commons.TextFieldRenderer.render(oRenderManager, oControl);

    However I think you just need to be careful regarding the ordering of rendering, setting styles etc.
