Checkbox + a4j:commandLink select

[svkap]

Hello.

I have several dynamically generated checkboxes which I need to check/uncheck using a4j:commandLink . Here is part of the code which is used to generate the checkboxes:

MethodExpression checkboxValueChangeExpression = expressionFactory
        .createMethodExpression(elContext,
                "#{bean.checkBoxClicked}", null,
                new Class[] { ActionEvent.class });
MethodExpressionActionListener checkboxValueChangeListener = new MethodExpressionActionListener(
        checkboxValueChangeExpression);

HtmlSelectBooleanCheckbox checkBox = new HtmlSelectBooleanCheckbox();
String checkboxId = "checkBox_id_" + getNumber();
checkBox.setId(checkboxId);
checkBox.setSelected(false);
checkBox.setStyleClass("checkbox");

HtmlAjaxSupport asCheckbox = new HtmlAjaxSupport();
String ajaxCheckboxId = AJAX_CHECBOX_ID_PREFIX
        + getNumber();
asCheckbox.setId(ajaxCheckboxId);
asCheckbox.setEvent("onclick");
asCheckbox.addActionListener(checkboxValueChangeListener);

checkboxValues.put(ajaxCheckboxId, false);

ValueExpression checkBoxValueExpression = expressionFactory
        .createValueExpression(elContext, "#{bean.checkboxValues."
                + ajaxCheckboxId + "}", Boolean.class);
checkBox.setValueExpression("value", checkBoxValueExpression);
checkBox.getChildren().add(asCheckbox);

Here is a slightly modified code of the commandLink method:

String id = AJAX_CHECBOX_ID_PREFIX + getNumber();
checkboxValues.put(id, true);

The problem is that although the reRender property is set to one of the parents of the checkboxes they are not updated in the UI (they remain unchecked). How can I make them refresh themselves?

I found the problem. Now I have to find the solution . The checkboxes are located in one ui:define tag and the command link is located in another. If both components are in the same ui:define it works. Otherwise I have to first click on one of the generated checkboxes and then it starts working perfectly (starts to refresh the UI).

Hi again.

Here are some strange observations...

Actually I have construction like that:

<ui:define ..

     <a4j:form id="form1">

          <h:panelGroup layout="block" id="test"

           ... some generaeted content (see the post above) ...

     </a4j:form>

</ui:define>

<ui:define ..

     <a4j:form id="form2">

          <a4j:commandLink ... reRender="test"  ...

     </a4j:form>

</ui:define>

When the page is loaded and I try to use the command link from form2 it does not work (it calls the backing bean and changes the checkbox value holder but does not refresh the UI). When I manually click on a checkbox then everything starts working and the command link refreshes the form1 UI.

I hope that I am not writing only to myself and someone can give me a hand
