Hide:
target.addJavaScript("document.getElementById('" +
component.getMarkupId() + "').style.display='none';");

target.addJavaScript("document.getElementById('" +
component.getMarkupId() + "').style.display='';");
It doesn't remove the component from the output stream, it just
manipulates the style of the tag itself.
