Ruby Forum Test > assert_select_rjs blocks failing in 1.2.4

I just updated my rails to 1.2.4 and now all my assert_select_rjs blocks
fail.

For example:

assert_select_rjs :replace_html, "test" do
  assert_select ".child"  #fails
end

with something like this for the rjs

page.replace_html "test", '<div class="child">Foo</div>'


Just wondering if anyone else is experiencing the same issue or has any
ideas why my assert_select_rjs blocks are failing.

Any help would be greatly appreciated.  Thanks!
