Dismissal of estafa case

I was charged with estafa by a former supplier of ours. The supposed amount owed to them was P16,000 and the case was filed on December 2011 yet we settled the amount in question on September 2011 well BEFORE the case was filed. We have an Official Recipt from the supplier to prove it. Upon realizing her mistake, the supplier immedeately filed an Affidavit of Desistance with the Branch in question and I already posted bail. We have a hearing tomorrow wherein the supplier will manifest their desire to no longer pursue the case of estafe against me. My question is is there any way the judge or the fiscal can try to prolong the case even if the party that filed it is no longer interested in pursuing the case? Is there a way I could be imprisoned even if I have already posted bail? Thank you.

sounds like you'll be ok if he actually filed his manifestation and appeared in court.
