This is not a big problem to me but it is something I wonder especially for recursived invoke step.
I have the following flow service fs1
MAP (Set Value = b to value)
INVOKE myFolder:fs2 (Output = value to variable output)
My Flow service fs2 :
MAP (Set value = a to value)
If I run fs1 I see two variables in pipeline
value (= a)
output (= a)
The variable value in output from fs2 override the value variable in fs1.
Is it existe something to prevent that ?
