Цитата:
For some reason (mainly related to the .Net Business Connector) the X++ code is sometimes cached and it is difficult to force it to take the new code.
The best way that I've found to force it to take the new code is to restart the Windows Process Activation Service in your local services on your Real-Time Service machine.
Т. е. нужно перезапустить службу Windows Process Activation Service и кэш должен сброситься.
