Error Parsing /page.xhtml: Error Traced[line: 42] The entity "nbsp" was referenced, but not declared

Question

I'd like to use non breaking spaces in my JSF page. I know, in plain HTML I could use   for this and this works fine. However, when I put those   in a Facelets page, then it errors as follows:

Error Parsing /page.xhtml: Error Traced[line: 42] The entity "nbsp" was referenced, but not declared.

How is this caused and how can I solve it?

Facelets is a XML based view technology. XML has only five predefined entities. The   is not among them. It works only when used in plain HTML or in legacy JSP (note: it doesn't work in JSPX as that's also XML based!).

To fix this, you either need to declare the entity yourself in the doctype of the very XHTML file containing the   entity,

<!DOCTYPE html [
    <!ENTITY nbsp "&#160;"> 
]>

or, better, use the (hexa)decimal notation instead:

&#xA0; or &#160;

In an average IDE it should be trivial to perform a "find and replace in all files" and replace every occurrence of   by  .

Use the hex or decimal notation. :-) – Nabin Aug 10 '16 at 02:41

For me the following doctype enables  :

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
        "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

Try using &#160;. for more information on entities you can refer following url HTML ISO-8859-1 Reference

Why did this get two negatives I wonder. It's maybe a bit too concise but it is correct. The entity was not defined in the doctype and it is defined when using the spec provided. A year later, someone posts the exact same thing and gets two upvotes. – Dilapidus Jul 18 '16 at 16:39
I agree with @Dilapidus, this worked perfect for me in Chrome and JBoss EAP 7 and Facelets Version 2.2 – JGlass Oct 03 '17 at 17:56

<![CDATA[ ]]> should work fine. This does not work inside attribute value, though.
Alternatively, as long as & is a predefined entity in XML, you could try &nbsp; - worked for me with XML based JSP. This should work within attributes as well.
