> Very strange error that happens every second or third time the form is
> submitted. Otherwise it works? I was orignially using 1.1 struts but just
> upgraded with the same issue to 1.2.4. I thinking it's a timing or threading
> issue, because of the way it works then doesn't work. The error message was
> a
> little better after going to struts 1.2.4. It suggested "This may be caused
> by whitespace in the label text". Although this would be strange considering
> that it works then doesn't work on the next submit. The other weird thing
> with this issue is that it seemed to work fine until I added a second
> DynaActionForm and a second method that is mapped in the same way as
> addcomponent action.
> Here's the DynaActionForm in struts-config :
> <form-bean name="addComponentForm"
> type="org.apache.struts.action.DynaActionForm">
> <form-property name="componentName" type="java.lang.String"
> initial="" />
> <form-property name="product" type="java.lang.String" />
> </form-bean>
> Here's the addcomponent action :
> <action path="/addcomponent"
> name="addComponentForm"
> scope="session"
> type="com.ihs.accumap.action.AdminFunctionsAction"
> validate="true"
> parameter="method"
> input="/addComponent.jsp">
> <forward name="addedcomponent" path="/addedcomponent.jsp"/>
> <forward name="failedtoaddcomponent" path="/addcomponent.jsp"/>
> <forward name="failure" path="/error.jsp"/>
> </action>
> Here's most of the jsp :
> <html:form action="/addcomponent">
> <html:hidden name="testListForm" property="product"/> <!-- we need the
> product
> name for this component as well -->
> <table VALIGN="top" cellpadding="3" cellspacing="1" WIDTH="%80"
> bgcolor="ffffcc" align=center>
> <tr>
> <td>Enter new component name : </td> <td><html:text size="25"
> name="addComponentForm" property="componentName"/></td>
> </tr>
> <td>
> <table align="right" bgcolor="ffffcc">
> <td align="right" >
> <html:submit property="method">
> <bean:message key="function.addcomponent"/>
> </html:submit>
> <html:reset/>
> </td>
> </tr>
> </table>
> </td>
> </tr>
> </table>
> </html:form>
> <br/>
> <table>
> <tr>
> <td><html:errors/></td>
> </tr>
> <tr>
> <td><html:messages id="mess"/></td>
> </tr>
> </table>
> </body>
> </html:html>
> Here's the important bits out of my Action class:
> public class AdminFunctionsAction extends LookupDispatchAction
> {
>
> protected Map getKeyMethodMap() {
> Map map = new HashMap();
> map.put("function.addtestcase", "addTestCase");
> map.put("function.addproduct", "addProduct");
> map.put("function.addcomponent", "addComponent");
> map.put("function.deletecomponent", "removeComponent" );
> return map;
> }
>
> public ActionForward addComponent( ActionMapping mapping,
> ActionForm form,
> HttpServletRequest request,
> HttpServletResponse response)
> throws Exception {
> // do add
>
> DynaActionForm addCompForm = (DynaActionForm) form;
>
> try{
> HttpSession session = request.getSession();
> UserAccountsView user = this.getUser( session );
>
>
> if( user.getUserName().length() < 1 )
> return (mapping.findForward("needtoauthenticate"));
>
> ComponentService compService = this.getComponentService( session );
>
> if ( compService.addComponent( addCompForm.get("componentName" ) +
> "",
> addCompForm.get("product") + "", user ) )
> return mapping.findForward("addedcomponent" );
> else return mapping.findForward("failedtoaddcomponent");
> } catch( Exception x ){
> x.printStackTrace();
> System.out.println("Blew up trying to add component....");
> return mapping.findForward("failedtoaddcomponent");
> }finally{
> addCompForm.set("componentName", "" );
> }
> }
> Here's the error:
> javax.servlet.ServletException: Request[/addcomponent] does not contain
> handler parameter named 'method'. This may be caused by whitespace in the
> label text.
