    Adding Ajax Support dynamically to HtmlInputText causes exception

    Gen Sys Newbie

      Hi All,

       

      I am trying to migrate from GlassFish v2.1 to GlassFish v3 and from RichFaces 3.3.2 to RichFaces 3.3.3 and I can feel myself almost there

       

      I am creating dynamically Components (in the example hardcoded HtmlInputText) in a Panel Group Component.

       

      Here is the code that we are using to create component:

       

      FacesContext context = FacesContext.getCurrentInstance();
              Application application = context.getApplication();
              ExpressionFactory factory = application.getExpressionFactory();
              ValueExpression expression = factory.createValueExpression(context.getELContext(),
                                                                         "#{user.value}",
                                                                         String.class);
              UIAjaxSupport supportOnKeyUp = (UIAjaxSupport) application.createComponent(HtmlAjaxSupport.COMPONENT_TYPE);
              supportOnKeyUp.setEvent("onkeyup");
              supportOnKeyUp.setEventsQueue("details");
              supportOnKeyUp.setReRender("greeting");
              UIAjaxSupport supportOnChange = (UIAjaxSupport) application.createComponent(HtmlAjaxSupport.COMPONENT_TYPE);
              supportOnChange.setEvent("onchange");
              supportOnKeyUp.setEventsQueue("details");
              supportOnChange.setReRender("greeting");
      
              // get the component type and create it dynamically
              UIInput input = (UIInput) application.createComponent("javax.faces.HtmlInputText");
              input.setValueExpression("value", expression);
              input.setId("paramValue");
              input.getChildren().add(supportOnKeyUp);
              input.getChildren().add(supportOnChange);
              
              if (mInputPanelGroup == null)
              {
                  mInputPanelGroup = (HtmlPanelGroup) application.createComponent(HtmlPanelGroup.COMPONENT_TYPE);
              }
              mInputPanelGroup.getChildren().clear();
              mInputPanelGroup.getChildren().add(input);
      

       

      And the panelGroup declaration:

       

      <h:panelGroup id="paramValueInputs" binding="#{user.inputPanelGroup}" 
                      layout="block" style="float: left;" />
      

       

      This code works fine with RichFaces 3.3.2.SR1, but when I migrated to RichFaces 3.3.3 Final I started to have this problem when the above code is executed:

      type Exception report

      message
      description
      The server encountered an internal error () that prevented it from fulfilling this request.

      exception

      root cause

      note The full stack traces of the exception and its root causes are available in the GlassFish Server Open Source Edition 3.0.1 logs.

      Here are and the stack traces:

      If I remove these 2 lines from the code (the above code snippet):

      input.getChildren().add(supportOnKeyUp);
      input.getChildren().add(supportOnChange);
      

      the HtmlInputText renders Ok and this exception is missing, but the Ajax Support is missing (normaly).

       

      Do you have any idea where the problem can be?

       

      Thanks in advance,

            Hi Harut,

             

            Thanks a lot for your reply !!!

             

            I tried this code:

             

            FacesContext context = FacesContext.getCurrentInstance();
                    Application application = context.getApplication();
                    ExpressionFactory factory = application.getExpressionFactory();
                    ValueExpression expression = factory.createValueExpression(context.getELContext(),
                                                                               "#{user.value}",
                                                                               String.class);
                    UIAjaxSupport supportOnKeyUp = (UIAjaxSupport) application.createComponent(HtmlAjaxSupport.COMPONENT_TYPE);
                    supportOnKeyUp.setEvent("onkeyup");
                    supportOnKeyUp.setEventsQueue("details");
                    supportOnKeyUp.setReRender("greeting");
                    UIAjaxSupport supportOnChange = (UIAjaxSupport) application.createComponent(HtmlAjaxSupport.COMPONENT_TYPE);
                    supportOnChange.setEvent("onchange");
                    supportOnKeyUp.setEventsQueue("details");
                    supportOnChange.setReRender("greeting");
            
                HtmlAjaxSupport mySupport = new HtmlAjaxSupport();
                mySupport.setEvent("onclick");
                mySupport.setReRender(AjaxRendererUtils.asSet("details"));
                mySupport.setAjaxSingle(false);
             
                    // get the component type and create it dynamically
                    UIInput input = (UIInput) application.createComponent("javax.faces.HtmlInputText");
                    input.setValueExpression("value", expression);
                    input.setId("paramValue");
                input.getFacets().put("a4jsupport", mySupport);
                    //input.getChildren().add(supportOnKeyUp);
                    //input.getChildren().add(supportOnChange);
                    
                    if (mInputPanelGroup == null)
            

             

            But it fails again for me ... with the same exception ...

             

            Do you have any other idea what could be the problem?

             

            Thanks again in advance!

              Hi Rogger,

               

              Have you tried to create text component like this: input = new HtmlInputText(); ??(javax.faces.component.html.HtmlInputText)

                Hi Harut,

                 

                Thanks again for spending time on my issue!

                 

                I made the relevant changes and I got the same exception.

                 

                I am attaching the JSF page and the Backing Bean along with the list of the libraries that I am referencing in my project.
