hiya It seems the documentation is a bit patchy about this. (At least regarding fai-wiki and the webpage.)
Am I allowed to use task_error in self-written hooks? If yes: What exactly means e.g. "task_error 801 $RETVAL" ? Is there a list of error codes already in use? May I invent new ones? Background: I'm in the process of polishing up my custom extrbase hook. It would be nice to properly signal 'something went wrong' (like missing requirements, runtime errors etc.) tschüß thomas
