Unable to reRender programatically using A4J in custom compo

[ahsan_cse2004]

Hi,
I am new to JSF and stuck with reRender functionality of Ajax4Jsf. I have to write an ajax enabled custom JSF component that contains several simple child components such as text box and selectOneMenu. for the convinience I assume one text box and one combo box. I have to update the content of text box when I change the value in selectOneMenu. but I am unable to do so, Everything is working fine as per JSF life cycle. Here is the code of my encodeBegin method.

public void encodeBegin(FacesContext context) throws IOException {
 super.encodeBegin(context);
 this.getChildren().clear();
 Application application = FacesContext.getCurrentInstance().getApplication();

 HtmlForm htmlForm = new HtmlForm();
 htmlForm.setId("reportConfigureForm");
 this.getChildren().add(htmlForm);

 HtmlSelectOneMenu htmlSelectOneMenu = new HtmlSelectOneMenu();
 htmlSelectOneMenu.setId("selectedReportType");
 htmlSelectOneMenu.setStyleClass("dropdown");
 htmlSelectOneMenu.setRequired(true);

 ValueBinding valueBinding = application.createValueBinding("#{" + getReportBeanName() + ".selectedReport}");
 htmlSelectOneMenu.setValueBinding("value", valueBinding);

 UISelectItems uiSelectItems = new UISelectItems();
 List<SelectItem> selectItems = new ArrayList<SelectItem>();
 for (Map.Entry<String, String> report : getReportBean().getReports().entrySet()) {
 selectItems.add(new SelectItem(report.getKey(), report.getValue()));
 }
 uiSelectItems.setValue(selectItems.toArray(new SelectItem[selectItems.size()]));
 htmlSelectOneMenu.getChildren().add(uiSelectItems);

 HtmlAjaxSupport htmlAjaxSupport = new HtmlAjaxSupport();
 htmlAjaxSupport.setEvent("onchange");
 htmlAjaxSupport.setReRender("testInputText");
 htmlSelectOneMenu.getFacets().put("a4jsupport", htmlAjaxSupport);

 HtmlInputText htmlInputText = new HtmlInputText();
 htmlInputText.setId("testInputText");
 ValueBinding testInputTextBinding = application.createValueBinding("#{" + getReportBeanName() + ".selectedReport}");
 htmlInputText.setValueBinding("value", testInputTextBinding);

 htmlForm.getChildren().add(htmlSelectOneMenu);
 htmlForm.getChildren().add(htmlInputText);
 }

What i think is that I am passing the invalid component id tp setReRender method thats why it is not getting rendered. Please let me know if I am doing wrong, or point me to any tutorial for the same. Also please point me to any better ways of doing the same. I am also not very happy about the way I populated the htmlSelectOneMenu. I thought that for every JSF tag we have corresponding java class but was unable to find one corresponding to <f:selectItems>, hence I used above way for populating the htmlOneMenu.

Thanks in Advance

Ahsan,

f:selectItems corresponds to javax.faces.component.UISelectItems.

Please see this topic: http://jboss.com/index.html?module=bb&op=viewtopic&t=145044

Thanks nbelaevski,
As you can see that I did the same for populating the htmlSelectOneMenu. Howerver my main issue remains the same, writing an Ajax Enabled Complex JSF component using composition of different simple JSF components. I will be obliged if you can provide me the resource/help in this regard.

Thanks
Ahsan
