Rails - Sep 2007 - checking for elements before replace_html on it

I do a whole lot of this from my controllers:

render :update do |page|
     page.replace_html ''someUniqueID'', "Some
content"
end

For one reason or another, sometimes this code is delayed and by the
time it executes "someUniqueID" is no longer on the page.  I need to
work an if statement in somewhere to verify that
''someUniqueID'' is
still present on the page before the replace_html gets fired off.

I''ve tried:

if page[''someUniqueID'']
Always returns true, even if someUniqueID is present

page.select(''#someUniqueID'').first.replace_html
''someContent''
With this, somehow "replace_html" gets converted to
"replaceHTML" and
then spits off:
    "replaceHtml is not a function"

Any other ideas??

Thanks!
