http://issues.apache.org/bugzilla/show_bug.cgi?id=32861 Summary: DynaActionForm and optionsCollection get exception Cannot create iterator... Product: Struts Version: 1.2.4 Platform: PC OS/Version: Windows XP Status: NEW Severity: normal Priority: P2 Component: Unknown AssignedTo: dev@struts.apache.org ReportedBy: [EMAIL PROTECTED] I having been trying to convert existing pages from extending ActionForm to DynaActionForm so that I don’t have to provide the set and get. I am having problems with the optionsCollection trying to get the iterator. The correct values are being obtained from the database and store via the LabelValueBean class. The getIterator method in OptionsCollectionTag should have a Collection, but it throw exception at line 351. Not sure, what is wrong. Thanks for you help. Greg My configuration is as follows: <form-bean name="SiteEditorForm" type="com.wsa.core.view.SiteEditorForm"> <form-property name="site" type="java.lang.String"/> <form-property name="arraylist" type="com.blacklake.business.db.Site"/> <form-property name="sitename" type="java.lang.String" initial=""/> <form-property name="sitedesc" type="java.lang.String" initial=""/> </form-bean> Partial listing of Site class that I am using: /************************************************************************** * * **************************************************************************/ public static Collection getArraylist() { Collection sitecollection = new ArrayList(); DatabaseConnection conn = null; String emessage = ""; tbSite dbsitelist = null; tbSite dbsite = null; try { // Initialize the database and tbAddress class. conn = new DatabaseConnection( "development" ); dbsitelist = new tbSite( conn.getConnection(), "default" ); // Get the list from the database. sitecollection.add( new LabelValueBean( "--add--","0") ); for( Iterator e=dbsitelist.searchAndRetrieveList().iterator(); e.hasNext(); ) { dbsite = (tbSite)e.next(); sitecollection.add( new LabelValueBean(dbsite.getField ("SiteName"), dbsite.getField("PK_Site")) ); }//for }//try catch( Exception e ) { emessage += e.getMessage(); }//catch finally { // Release the object for GC. dbsitelist = null; dbsite = null; // Close the database cleanly. conn.closeConnection(); conn = null; }//finally return( sitecollection ); } // getArraylist /************************************************************************** * * **************************************************************************/ public String toString() { ArrayList sites = (ArrayList)Site.getArraylist(); return( sites.toString() ); } // toString /************************************************************************** * * **************************************************************************/ public Iterator iterator() { ArrayList sites = (ArrayList)Site.getArraylist(); return( sites.iterator() ); //Vector sites = Site.getSiteOptions(); //return( sites.iterator() ); } // toString Reported exception: javax.servlet.ServletException: Cannot create iterator for [LabelValueBean[-- add--, 0], LabelValueBean[development, 1], LabelValueBean[test, 2], LabelValueBean[production, 3]] org.apache.jasper.runtime.PageContextImpl.doHandlePageException (PageContextImpl.java:825) org.apache.jasper.runtime.PageContextImpl.handlePageException (PageContextImpl.java:758) org.apache.jsp.wsa.siteEditor_jsp._jspService(siteEditor_jsp.java:140) 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) org.netbeans.modules.web.monitor.server.MonitorFilter.doFilter (MonitorFilter.java:362) root cause javax.servlet.jsp.JspException: Cannot create iterator for [LabelValueBean[-- add--, 0], LabelValueBean[development, 1], LabelValueBean[test, 2], LabelValueBean[production, 3]] org.apache.struts.taglib.html.OptionsCollectionTag.getIterator (OptionsCollectionTag.java:351) org.apache.struts.taglib.html.OptionsCollectionTag.doStartTag (OptionsCollectionTag.java:185) org.apache.jsp.wsa.siteEditor_jsp._jspx_meth_html_optionsCollection_0 (siteEditor_jsp.java:386) org.apache.jsp.wsa.siteEditor_jsp._jspx_meth_html_select_0 (siteEditor_jsp.java:358) org.apache.jsp.wsa.siteEditor_jsp._jspx_meth_html_form_0 (siteEditor_jsp.java:257) org.apache.jsp.wsa.siteEditor_jsp._jspService(siteEditor_jsp.java:101) 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) org.netbeans.modules.web.monitor.server.MonitorFilter.doFilter (MonitorFilter.java:362) note The full stack trace of the root cause is available in the Apache Tomcat/5.0.28 logs. -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
