iApp not working from 11.3 to 11.4 /Common folder

Hi James- I'd like to help, but I need some more information. Your comment about removing $arguments leads me to believe that the error is occurring during implementation, ie. after you click "Finished" to submit the iApp. I suppose that some command further into your iApp is calling tmsh_modify with arguments that, when handed to mcpd, are throwing an error. You should be able to determine which line is crying foul by looking at the debug output in /var/tmp/scriptd.out. Since the iApp stops execution when the error occurs, the offending command will be the last entry. If the cause is not obvious by then, reply to the post with the tail of scriptd.out and I will try to identify why the offending tmsh command behaves differently in 11.4. -Fred
