HisetOutputMarkupId sets the "id" attribute of the HTML tag. This generally must be set if the tag shall be updated by AJAX setOutputMarkupPlaceholderTag has the effect that a *hidden* component is still added to the HTML tree but - hidden. This is used, if the component is initially not visible (isVisible() == false) and would normally not leave a trace in the generated HTML file, thus it cannot be set visible by AJAX since it doesn't have a 'handle' to it. So it generally must be set to true if the component is to be updated by AJAX but is NOT initially visible.

Can anyone tell me the difference b/w SetoutputMarkupId(true) and SetOutputMarkupHolderTag(true)?
