Hi all, I want to do this:
My workflow accepts an input port. Within the workflow I can do two different things: a) If the input parameter has a value do something b) else if the input parameter has nothing (i.e. is not connected), do something. I have been trying to use boolean expressions (IsPresent) and a logical multiplexor but when the input port is not connected I get an error I can not solve. Please find attached the workflow, try to remove the external input port parameter to see the problem Cheers, Jose. -------------- next part -------------- A non-text attachment was scrubbed...
