In my migration of code from OpenBlueDragon to Lucee, I have to use the cfajaxproxy extention. In doing so, I found a bug. it appears when you use setSyncMode(), it does not clear the setCallbackHandler(), and when the synchronous call returns, it fires off the previous set setCallbackHandler().
I know this is a no longer supported function, so I do not know if this is worth updating. Evently I will move this code base over to the html5 version, but I figure if the extention is available for install, should it not be fixed?
