I don't exactly know if it's this problem, but what Java types to you have in your SelectItems value. Perhaps the value binding of the selectOneRadio is binded to the wrong Java Type... You know what I mean...
For example: If your SelectItem consists of (int, String) then the value binding of the selectOneRadio Component must be bind to an int... I hope I don't tell you nonsense, because I'm also a beginner in JSF but I got the same error stack some days ago and this was the problem. regards, Andy -----Ursprüngliche Nachricht----- Von: Caroline Jen [mailto:[EMAIL PROTECTED] Gesendet: Mittwoch, 28.

Meanwhile, I am unable to find the JSF version in the IDE I use. I am uncertain if my problem is related to the version 1.1 of JSF or the problem is with my code. I have put a ValueChangeListener for my radio button. I have two radio buttons. And I have two list boxes. List box A will be displayed if the first radio button is clicked by users. List box B will be displayed if the second radio button is clicked by users. To have something displayed in the list box when the web page is "first" rendered, I would like to show a default radio button (the first radio button) and display the list box A. But, my code has a "runtime" error: quote: ------------------------------------------------------ java.lang.IllegalArgumentException: Conversion Error setting value ''{0}'' for ''{1}''. ------------------------------------------------------ My code is show below. In my jsp page, I try to construct a set of radio buttons and a list box: code: ----------------------------------------------------- <h:selectOneRadio value="#{dataManagementBean.dataTransferTypeItems[0]}" layout="pageDirection" onchange="submit()" immediate="true" valueChangeListener="#{dataManagementBean.showRecordList}"> <f:selectItems value="#{dataManagementBean.dataTransferTypeItems}"/> </h:selectOneRadio> <h:selectOneListbox value="#{dataManagementBean.record}" required="true" immediate="true"> <f:selectItems value="#{dataManagementBean.recordItems}"/> </h:selectOneListbox> ---------------------------------------------------- In my backing bean, I have: code: ----------------------------------------------------- private SelectItem[] dataTransferTypeItems; private Map records; private SelectItem[] recordItems; dataTransferTypeItems = new SelectItem[] { new SelectItem("import", "Records available for import"), new SelectItem("export", "Records available for export") }; public SelectItem[] showRecordList( ValueChangeEvent event ) { FacesContext context = FacesContext.getCurrentInstance(); if ( ( ( String )event.getNewValue() ).equals( "import") ) { recordItems = ( SelectItem[] ) records.get( "import" ); } else { recordItems = ( SelectItem[] ) records.get( "export" ); } context.renderResponse(); return recordItems; } ---------------------------------------------------- This is how I contruct my "records", which is a Map: code: ---------------------------------------------------- records = new HashMap(); records.put( "import", new SelectItem[] { new SelectItem( "import1", "HAFMDS -- FAC_SAR" ), new SelectItem( "import2", "LOCAL -- AFSC_SUB" ), new SelectItem( "import3", "LOGMOD -- Chalk" ), new SelectItem( "import4", "MDS -- Authorizations" ), new SelectItem( "import5", "MDS -- Wartime_Inplace" ) } ); records.put( "exports", new SelectItem[] { new SelectItem( "export1", "LOGFOR -- UTA" ), new SelectItem( "export2", "MISSION -- DESIGN_NUM" ), new SelectItem( "export3", "AUTH -- Upgrade" ), new SelectItem( "export4", "MISCAP -- Basic" ), new SelectItem( "export5", "DEPID -- HQ_FAM_PHONE" ) } ); --------------------------------------------------- The runtime error message is: quote: ---------------------------------------------------- java.lang.IllegalArgumentException: Conversion Error setting value ''{0}'' for ''{1}''. com.sun.faces.util.Util.getSelectItems(Util.java:628) com.sun.faces.renderkit.html_basic.MenuRenderer.getOptionNumber(MenuRenderer.java:488) com.sun.faces.renderkit.html_basic.MenuRenderer.renderSelect(MenuRenderer.java:465) com.sun.faces.renderkit.html_basic.MenuRenderer.encodeEnd(MenuRenderer.java:430) javax.faces.component.UIComponentBase.encodeEnd(UIComponentBase.java:720) javax.faces.webapp.UIComponentTag.encodeEnd(UIComponentTag.java:623) javax.faces.webapp.UIComponentTag.doEndTag(UIComponentTag.java:546) com.sun.faces.taglib.html_basic.SelectOneListboxTag.doEndTag(SelectOneListboxTag.java:521) org.apache.jsp.pages.screen1_jsp._jspx_meth_h_selectOneListbox_0(screen1_jsp.java:383) org.apache.jsp.pages.screen1_jsp._jspx_meth_h_form_0(screen1_jsp.java:212) org.apache.jsp.pages.screen1_jsp._jspx_meth_f_view_0(screen1_jsp.java:164) org.apache.jsp.pages.screen1_jsp._jspService(screen1_jsp.java:129) org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:94) javax.servlet.http.HttpServlet.service(HttpServlet.java:802) org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:324) org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:292) org.apache.jasper.servlet.JspServlet.service(JspServlet.java:236) javax.servlet.http.HttpServlet.service(HttpServlet.java:802) com.sun.faces.context.ExternalContextImpl.dispatch(ExternalContextImpl.java:322) com.sun.faces.application.ViewHandlerImpl.renderView(ViewHandlerImpl.java:130) com.sun.faces.lifecycle.RenderResponsePhase.execute(RenderResponsePhase.java:87) com.sun.faces.lifecycle.LifecycleImpl.phase(LifecycleImpl.java:200) com.sun.faces.lifecycle.LifecycleImpl.render(LifecycleImpl.java:117) javax.faces.webapp.FacesServlet.service(FacesServlet.java:198) --------------------------------------------------- --- Paul Klaer <[EMAIL PROTECTED]> wrote: > This bug has no Exception.
