I have a transition that will Perform another transition from Actions, the second transition is a quick transition that runs a webservice. BUT as a Post-transition action on the quick transition we have an appscript that checks field values if it should be run or not. If not it sends a Shell.RedoMessage. That is all fine and the webservice is only running when is should but when it shouldn't we get a system error message "Unable to execute transition transitionname on projectname Itemnumber. One or more fields are invalid"
So functionality is good but I don't want the error message
