everything looks OK to me
check whether there are any JS errors in the browser's Dev Tools console.

OnChangeAjaxBehavior.onUpdate() not called
I need to make a calculator like this:
x =
x =
... and so on for a variable number of rows...
I need the user to input a number in one of the input text fields.
I need the other input text fields to update themselves while the user types
the number digits, so that all input fields show exactly the same number at any
time.
I need the results to update themselves also while the user types the digits.
here is my html snippet
x
5.2
=
52
and Java code:
Label fixed = new Label("fixed", myFixedNumber);
add(fixed);
final TextField input = new TextField<>("input");
add(input);
input.add(new OnChangeAjaxBehavior()
{
@Override
protected void onUpdate(AjaxRequestTarget target)
{
// this never gets called
}
});
Label total = new Label("total");
add(total);
The problem is that onUpdate() never gets called. Please note that I'm not
using any because I do not need any (I don't need the user to submit
anything), but I need to make calculations server side because the fixed value
is known there.
Is it possible to have onUpdate() called without using a form? if yes, what am
I doing wrong?

Re: How to Embed PDF in a Web Page
Hi, You need to use ResourceLink because you need "Content-Disposition: Inline" response header to tell the browser to *try* to render the pdf. With DownloadLink it will be "Content-Disposition: Download" and the browser will popup a confirm dialog to the user asking her where to store the file. But to work the browser needs to know how to render PDFs (either out of the box, or with a plugin). If there is no such support then the browser will offer to download the file.
