Hi again, I read and followed the instructions on the link you sent me... but no way. First, I can not find an actor which makes "conditional expressions". Second, the attached workflow does almost what I want: When a value is set for the port, it is detected and also is detected a missing value. The thing is that I would like to modify the outputs. Instead of printing a single constant string I would like to do this:
a) If true (if input is present): print a string consisting of a string plus the value of the input. b) if false, print an empty string. This is ok as I just need to change the current value to an empty string. Can you please have a look at it?. Thanks in advance, Jose. -------------- next part -------------- A non-text attachment was scrubbed...
