[kepler-users] using undefined input port

[José Román Bilbao Castro]

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.
