Dear Jerry
Thanks for the information and the advice, but I am not sure how to
redesign to avoid putting anything into <head></head>. Specifically
the component uses some CSS that is indepdent of any other CSS in the
document, and therefore I wanted to embed it in the head so that
multiple instances of the component only emit it once. I suppose I
can put it into the <body> but it just seemed cleaner to shove it in
<head>.
Any suggestions on redesign would be appreciated, I am very new to
WebObjects so any tips are appreciated.
Vincent
