Hi, I have an <s:link view="/Page.xhtml"> | <f:param name="realise" value="true" /> | </s:link> The Page.xhtml has a backing Statefull Bean (Conversation scope) with an attribute with its getter and setter: @RequestParameter("realise") | private boolean realise; I have a method in this bean which prints on the console "realise" value. When I click on the s:link the page Page.xhtml shows up correctly and the "realise" value is printed on the console. When I click on any s:link on Page.xhtml redirecting to the same page everything is Ok. But when I click on any h:commandlink with an action or s:link with an action i'm redirected to debug page with this exception: Could not set field value by reflection: MyBean.realise on: MyPackage.MyBean with null value I also put an f:param in the commandlink but noway! What is the problem? Using Jboss Seam 1.2.1.GA + JBoss Server 4.0.5.GA View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4087106#...
