waitfornottext not present in selenium rc

Question

I am testing using Selenium RC but most of the waitforNottext etc are not present in it. Any idea why?

Am I missing something

Answer 1

If you use java and Selenium RC then can change condition to negation i.e. -

while(count>0)
 if(!selenium.isTextPresent("text")) {
  Thread.Sleep(1000)[
 }
 count--;
}
