[JBoss Seam] - Page parameters - change value - jboss-user

Wednesday, 11 April 2007

There is probably something I got wrong - but here is my case:

  | <?xml version='1.0' encoding='UTF-8'?>
  | <html xmlns="http://www.w3.org/1999/xhtml"
  |       xmlns:h="http://java.sun.com/jsf/html">
  | <head></head>
  | <body>
  | <h:form>
  |     #{test}
  | </h:form>
  | </body>
  | </html>
  | 

and a page parameter mapping

  | <page view-id="/test.xhtml">
  |     <param name="testValue" value="#{test}"/>
  | </page>
  | 

Requsting the page /test.jsf?testValue=123 outputs 123
However, if requesting /test.jsf?testValue=456 afterwards
123 is still displayed.

Note that this only happens if including the form on the page.

I was planning of using the page parameter to make my pages bookmarkable, but it seems to
be trickier then I though. There must me something obvious that I'm missing?

My workaround for now has been to extend SeamPhaseListener and make sure
Pages.instance().applyRequestParameterValues(facesContext) is always executed in the
afterRestoreView() function. This feels a bit scary, since I'm not that familiar with
the inner workings of this stuff.

Any suggestions?

I'm running Seam 1.2.1.GA, Facelets 1.1.11 and MyFaces 1.1.6 nighly build from March.
