Hello, i do have a rather complex application which does not make use of ajax4jsf yet. My environment seam 1.1.6 myfaces and facelets that comes with seam running on tomcat 5.5 In this app there is this method: | @Out(scope=CONVERSATION, required=false) private MethodType methodType; | [....] | @Begin(join=true) | public String addPCRAnalysis() { | log.debug("addPCRAnalysis bazExperiment "+((bazExperiment==null)?"ist null":bazExperiment.getExperimentCode())); | log.debug("addPCRAnalysis Type "+((bazExperiment==null)?"ist null":bazExperiment.getType())); | methodType = bazExperiment.getType(); | return "ADD_ANALYSIS"; | } | After this method a page is rendered where the bean 'PrimerListBacking' is called which injects methodType. @In | private MethodType methodType; | This seems to work perfectly. Now i tried to make my app ajax4jsf aware. I downloaded version 1.0.6 and configurted my app. The two libs ajax4jsf.jar and oscache-2.3.2.jar where copied to WEB-INF/lib. After that i deleted the view-handler from faces-config.xml And added this part to web.xml <filter> | <display-name>Ajax4jsf Filter</display-name> | <filter-name>ajax4jsf</filter-name> | <filter-class>org.ajax4jsf.Filter</filter-class> | <init-param> | <param-name>forceparser</param-name> | <param-value>false</param-value> | </init-param> | </filter> | <filter-mapping> | <filter-name>ajax4jsf</filter-name> | <servlet-name>Faces Servlet</servlet-name> | <dispatcher>REQUEST</dispatcher> | <dispatcher>FORWARD</dispatcher> | <dispatcher>INCLUDE</dispatcher> | </filter-mapping> | <context-param> | <param-name>org.ajax4jsf.VIEW_HANDLERS</param-name> | <param-value>org.jboss.seam.ui.facelet.SeamFaceletViewHandler</param-value> | </context-param> | | <filter> After doing so, i receive an required exception for methodType. What is going on? Can i provide additional info. For the purpose of testing i removed all myfaces filters from faces-config and tried again.
