Hello, I have a simple action link that update a zone with a Block. I have implemented the Layout pattern and my Layout template starts with
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:t="http://tapestry.apache.org/schema/tapestry_5_0_0.xsd"> ... </html> If the block returned by the method associated with my actionlink contains HTML Markup like a simple div, I have this error : [ERROR] RequestExceptionHandler Processing of request failed with uncaught exception: Namespace prefix for URI 'http://www.w3.org/1999/xhtml' is not defined. java.lang.RuntimeException: Namespace prefix for URI 'http://www.w3.org/1999/xhtml' is not defined. ... Can a block contains HTML Markup ? I have take a look at the ZoneDemo sample given with the Tapestry sources, and block contains only text. The errors seems to be due to the partial request handling, when a HTML element is transformed "toMarkup", it looks for the parent to know the mapping for the "http://www.w3.org/1999/xhtml" namespace and fails because parent is "null" due to partial rendering. I'm working with Tapestry 5.0.11. Thanks in advance, Christophe. ________________________________ Ce message et les pi?ces jointes sont confidentiels et r?serv?s ? l'usage exclusif de ses destinataires.
