Peace Software commented on MYFACES-1342: ----------------------------------------- I should have pointed out that this issue only occurs when we are using the Trinidad jars. As I understand it when you use Trinidad it overrides the render kit for all of the components, and I think it is because of this that we are having an issue. I believe this issue belongs back on the Trinidad project. > Can't add nested param tags to an h:output link > ----------------------------------------------- > > Key: MYFACES-1342 > URL: http://issues.apache.org/jira/browse/MYFACES-1342 > Project: MyFaces Core > Type: Bug > Environment: We are using facelets > Reporter: Peace Software > Priority: Minor > > When we add a nested param tag to the an output link as shown below we get a > stack trace on the page > <h:outputLink value="BusinessObjectPropertySummary"> > <f:param name="buisnessObjectClass" > value="#{businessObjectDetails.className}"/> > <h:outputText value="#{businessObjectDetails.name}"/> > </h:outputLink> > java.lang.NullPointerException: charsetName > at java.io.OutputStreamWriter.<init>(OutputStreamWriter.java:81) > at java.net.URLEncoder.encode(URLEncoder.java:189) > at > org.apache.myfaces.renderkit.html.HtmlLinkRendererBase.addParameterToHref(HtmlLinkRendererBase.java:428) > at > org.apache.myfaces.renderkit.html.HtmlLinkRendererBase.addChildParametersToHref(HtmlLinkRendererBase.java:360) > at > org.apache.myfaces.renderkit.html.HtmlLinkRendererBase.renderOutputLinkStart(HtmlLinkRendererBase.java:376) > at > org.apache.myfaces.renderkit.html.HtmlLinkRendererBase.encodeBegin(HtmlLinkRendererBase.java:95) > at > javax.faces.component.UIComponentBase.encodeBegin(UIComponentBase.java:307) > at > org.apache.myfaces.renderkit.RendererUtils.renderChild(RendererUtils.java:441) > at > org.apache.myfaces.renderkit.RendererUtils.renderChildren(RendererUtils.java:427) > at > org.apache.myfaces.renderkit.RendererUtils.renderChild(RendererUtils.java:448) > at > org.apache.myfaces.renderkit.html.ext.HtmlTableRenderer.renderColumnBody(HtmlTableRenderer.java:206) > at > org.apache.myfaces.renderkit.html.HtmlTableRendererBase.encodeColumnChild(HtmlTableRendererBase.java:168) > at > org.apache.myfaces.renderkit.html.ext.HtmlTableRenderer.encodeColumnChild(HtmlTableRenderer.java:161) > at > org.apache.myfaces.renderkit.html.HtmlTableRendererBase.encodeInnerHtml(HtmlTableRendererBase.java:154) > at > org.apache.myfaces.renderkit.html.HtmlTableRendererBase.encodeChildren(HtmlTableRendererBase.java:94) > at > org.apache.myfaces.renderkit.html.ext.HtmlTableRenderer.encodeChildren(HtmlTableRenderer.java:57) > at > javax.faces.component.UIComponentBase.encodeChildren(UIComponentBase.java:319) > at > com.sun.facelets.tag.jsf.ComponentSupport.encodeRecursive(ComponentSupport.java:234) > at > com.sun.facelets.tag.jsf.ComponentSupport.encodeRecursive(ComponentSupport.java:239) > at > com.sun.facelets.tag.jsf.ComponentSupport.encodeRecursive(ComponentSupport.java:239) > at > com.sun.facelets.tag.jsf.ComponentSupport.encodeRecursive(ComponentSupport.java:239) > at > com.sun.facelets.tag.jsf.ComponentSupport.encodeRecursive(ComponentSupport.java:239) > at > com.sun.facelets.FaceletViewHandler.renderView(FaceletViewHandler.java:554) > at > com.peace.externalInteraction.web.jsf.PeaceFaceletViewHandler.renderView(PeaceFaceletViewHandler.java:62) > at > org.apache.myfaces.adfinternal.application.ViewHandlerImpl.renderView(ViewHandlerImpl.java:175) > at > org.apache.myfaces.lifecycle.LifecycleImpl.render(LifecycleImpl.java:352) > at javax.faces.webapp.FacesServlet.service(FacesServlet.java:107) > at > org.apache.myfaces.webapp.MyFacesServlet.service(MyFacesServlet.java:74) > at > com.peace.externalInteraction.web.OmniServlet.service(OmniServlet.java:78) > at > org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:252) > at > org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) > at > org.apache.myfaces.adfinternal.webapp.AdfFacesFilterImpl._invokeDoFilter(AdfFacesFilterImpl.java:320) > at > org.apache.myfaces.adfinternal.webapp.AdfFacesFilterImpl._doFilterImpl(AdfFacesFilterImpl.java:289) > at > org.apache.myfaces.adfinternal.webapp.AdfFacesFilterImpl.doFilter(AdfFacesFilterImpl.java:213) > at > org.apache.myfaces.adf.webapp.AdfFacesFilter.doFilter(AdfFacesFilter.java:90) > at > org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:202) > at > org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) > at > org.apache.myfaces.component.html.util.ExtensionsFilter.doFilter(ExtensionsFilter.java:122) > at > org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:202) > at > org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) > at > com.peace.externalInteraction.web.jsf.ViewModeFilter.doFilter(ViewModeFilter.java:29) > at > org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:202) -- This message is automatically generated by JIRA. -
