Integrating Shale with Ajax4JSF
Hello, I tried vainly to use Shale 1.0.4 with Ajax4JSF. When I put some ajax component onto my page and try to open it, I receive a NullPointerException: javax.servlet.ServletException javax.faces.webapp.FacesServlet.service(FacesServlet.java:256) org.apache.myfaces.webapp.filter.ExtensionsFilter.doFilter(ExtensionsFilter.java:147) org.ajax4jsf.webapp.BaseXMLFilter.doXmlFilter(BaseXMLFilter.java:141) org.ajax4jsf.webapp.BaseFilter.doFilter(BaseFilter.java:281) de.uni_muenster.easy.web.filters.SecurityFilter.doFilter(SecurityFilter.java:48) org.apache.shale.application.faces.ShaleApplicationFilter.doFilter(ShaleApplicationFilter.java:267) org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) java.lang.NullPointerException org.ajax4jsf.renderkit.AjaxRendererUtils.buildAjaxFunction(AjaxRendererUtils.java:390) org.ajax4jsf.renderkit.html.AjaxFormRenderer.doEncodeBegin(AjaxFormRenderer.java:131) org.ajax4jsf.renderkit.RendererBase.encodeBegin(RendererBase.java:101) javax.faces.component.UIComponentBase.encodeBegin(UIComponentBase.java:788) javax.faces.component.UIComponent.encodeAll(UIComponent.java:884) javax.faces.component.UIComponent.encodeAll(UIComponent.java:892) com.sun.facelets.FaceletViewHandler.renderView(FaceletViewHandler.java:592) org.ajax4jsf.application.ViewHandlerWrapper.renderView(ViewHandlerWrapper.java:108) org.ajax4jsf.application.AjaxViewHandler.renderView(AjaxViewHandler.java:243) com.sun.faces.lifecycle.RenderResponsePhase.execute(RenderResponsePhase.java:106) com.sun.faces.lifecycle.LifecycleImpl.phase(LifecycleImpl.java:251) com.sun.faces.lifecycle.LifecycleImpl.render(LifecycleImpl.java:144) javax.faces.webapp.FacesServlet.service(FacesServlet.java:245) org.apache.myfaces.webapp.filter.ExtensionsFilter.doFilter(ExtensionsFilter.java:147) org.ajax4jsf.webapp.BaseXMLFilter.doXmlFilter(BaseXMLFilter.java:141) org.ajax4jsf.webapp.BaseFilter.doFilter(BaseFilter.java:281) de.uni_muenster.easy.web.filters.SecurityFilter.doFilter(SecurityFilter.java:48) org.apache.shale.application.faces.ShaleApplicationFilter.doFilter(ShaleApplicationFilter.java:267) org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) The reason is that Ajax4JSF relies on the fact that either facesContext.getViewRoot() is an AjaxViewRoot container or that the ajaxForm's parent (or grand parent and so on) is an AjaxViewRoot. But using Shale the facesContext.getViewRoot() is an instance of ShaleViewRoot (the form's parent is that same ShaleViewRoot object). As this issue is not resolved with the latest 1.1.0 SNAPSHOT I would like to ask you kindly to give full Ajax4JSF support. Thank you very much Dominik

Using nullValue-properties with Shale Tiger
Hello, I am doing my first steps with Shale and ran into some problems with Shale Tiger. I think the @Property-annotation has the same semantics as the managed-property thing in the faces-config.xml. Main difference seems to be that @Property only supports non-null values whereas managed-property also has a subproperty null-value. I had a look at the ManagedPropertyConfig.class in the Tiger source code and found out that there actually is also a nullValue-property for Tiger-Managed properties. But how can I tell with a @Property annotation that I want that property to start with a null value? I tried the following: 1.@Property(name=newUser, value=null) private User newUser; That doesn't work as java tells me that value must be a constant expression. 2. @Property(name=newUser, value=) private User newUser; That doesn't work as shale searches for a converter from String to User but cannot find one. That results in a null pointer exception. Maybe I am missing something but it seems that shale tiger is not able to work wih nullValue-properties if I'd like to define them using annotations. I hope someone can help me find out how to use tiger here. Thanks a lot in advance and best regards Dominik
