JSF remove invalid component from page

i'm using JSF 1.2 with IceFaces 1.8.

On my page i got an selectOneListbox, wh开发者_如何转开发ich content (e.g. EQUAL TO, BETWEEN, IN) triggers inputText fields to be rendered. If EQUAL TO is choosen one field is rendered else if BETWEEN is chossen two fields are rendered.

If my validation on the inputText field fails, and i change the content of the listbox the explained rendering does not work.

So has anyone a suggestion how to remove an "invalid" component from the html page?

I set invalid components to invisible.

I use the visible="#{myManagedBean.fieldVisible}" attribute for the component in my JSF page and public boolean isFieldVisible() { return flag; } in my Managed Bean to achieve this.
