My cop didn't show up to my traffic court hearing, shouldn't the case have been deferred?

In short, today I showed up for my traffic court hearing I was assigned after I called the court to tell them I would be pleading not guilty to the ticked I given and would like a trial. Once the judge called me up to the stand I pleaded not guilty and the judge told me another court date would be mailed to my house as the police officer who gave me my ticket was not available. I thought if a police officer doesn't show for a trial the case is deferred? I went back to the prosecutor to ask him about this but he just blew it off and told me to have a nice day.... Seeing how things went, I guess if a cop doesn't show up for a court case the case isn't always deferred? Anyone else have any similar experiences like this? I was only charged with a minor moving violation so a court hearing was not mandatory. Any wisdom that could be shed on this situation would be appreciated. Thanks.
