Does init() delayed in the onLoad: onLoad="setTimeout('init();', 0);"
Not sure if this will make a difference but it's simple enough to try.
Otherwise I can tell from the jsp code snippets. Is there a DOM node
with id="components"? Does G.getElementsByTagName("components") return
an array of elements? If not, then that'd explain why I is null.
