add action to a UISelectItem (RF 333)

[shikida]

Hi

I am generating programatically a list of options.

I can set an ajax action to the whole component just like this

        HtmlSelectManyCheckbox list = (HtmlSelectManyCheckbox)application.createComponent(HtmlSelectManyCheckbox.COMPONENT_TYPE);
       
        ValueExpression listaMultiBinding = exprFactory.createValueExpression(elContext,"#{test.value.list}",String.class);
        list.setValueExpression("value", listaMultiBinding);
       
        UISelectItems selectItems = (UISelectItems)application.createComponent(UISelectItems.COMPONENT_TYPE);
        List<SelectItem> options = new ArrayList<SelectItem>();
       
        for(int i=0;i<10;i++){
            options.add(new SelectItem(i, "option #"+i));   
        }
       
//        UISelectItem item1 = (UISelectItem)application.createComponent(UISelectItem.COMPONENT_TYPE);
       
        selectItems.setValue(options);
        list.getChildren().add(selectItems);
       
        UIAjaxSupport ajax2 =(UIAjaxSupport)application.createComponent(UIAjaxSupport.COMPONENT_TYPE);
        ajax2.setEvent("onchange");
        ajax2.setActionExpression(...);
        list.getChildren().add(ajax2);
       
        children.add(list);

What I want is to enable/disable other components in the same screen, according to each option selected. They´re also dynamically generated.

What´s the best way for this? Is there any way to bind actions to each option instead to the whole HtmlSelectManyCheckbox?

TIA

easy way use javascript <div> tag to hide the component and show the component.

[sivaprasad9394]

try using rendered attribute to show the component and hide the component,like set some value in backing bean and if the property value ="that value in backing bean" show the component.

I don´t want to hide, I want to disable.

And I can´t use the rendered attribute in a UIComponent object

the solution I´ve found was to send several javascript commands after the page rendering disabling via jquery.
