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,or, better, use the (hexa)decimal notation instead:
In an average IDE it should be trivial to perform a “find and replace in all files” and replace every occurrence of
by .
