User Control does not work

Question

I am taking the first steps regarding User Controls in Genexus and I started by creating this simple user control:

Jscript Runtime Render:

function test1($)
{
    this.Width;
    this.Height;

    this.show = function()
    {
        ///UserCodeRegionStart:[show] (do not remove this comment.)
        var buffer = "<p> hello </p>";
        this.setHtml(buffer);

        ///UserCodeRegionEnd: (do not remove this comment.)
    }
    ///UserCodeRegionStart:[User Functions] (do not remove this comment.)

    ///UserCodeRegionEnd: (do not remove this comment.):
}

The only tab I edited was the one where I just added the lines:

        var buffer = "<p> hello </p>";
        this.setHtml(buffer);

When I add user control to a web panel the result after running the application is an empty web page, not even the page footer and header.

I also followed the Helloworld tutorial to make a User control, but the result of the page is also totally empty (blank). What is wrong here? Something remains to be done?

I’m using trial version 3.

You have already run a Genexus.exe /install with genexus closed and then force Build on the object you want to test
