Question

#{'«'.concat(text)}

It's ok. But

#{'«'.concat(text)}

Exception:
javax.faces.view.facelets.FaceletException: Error Parsing /page.xhtml: Error Traced[line: 45] The entity "laquo" was referenced, but not declared.

Answer 1

If you use facelets then this is the expected behaviour.
You should use the hexadecimal notation or declare the entity you wish to use in the doctype.Have a look at these websites for more details.
