[jbossseam-issues] [JBoss JIRA] Updated: (JBSEAM-691) Ability to turn off page parameter appending for s:link

Ability to turn off page parameter appending for s:link ------------------------------------------------------- Key: JBSEAM-691 URL: http://jira.jboss.com/jira/browse/JBSEAM-691 Project: JBoss Seam Issue Type: Feature Request Components: JSF Reporter: Christian Bauer Assigned To: Gavin King Priority: Minor Fix For: 1.1.5.GA You have basically two choices how you can transport state in a RESTful way between pages: A. Use <s:link>, append the parameters manually, and pull the state on the target pages' backing bean with @RequestParameter B. Use <s:link>, and let Seam automatically append the parameters that the target page requires (pages.xml parameters), set the values on the backing bean that way Option A seems to be a good overall strategy if you rarely have to pass parameters around. Option B is the "always pass parameters around" option. In practice, you need a mixed strategy frequently. You might go for option B because it is so convenient, but disabling the parameters when _not_ needed (because the target page treats them conditionally, for example) requires customized <s:link> declarations, like: <s:link action="foo"><f:param name="aParamIDoNotWantToPropagate" value=""/></s:link> Effectively, page parameters currently guarantee that every link to that page contains the specified parameters. I want to sometimes disable this guarantee, e.g. with <s:link parameters="none"/>
