| Output based on current and previous input values [message #776473] |

What I have now is a simple transformation where one object in the source corresponds with one object in the destination, and this is rather straight forwards.
However, I wish to keep a memory of the previous input, as I wish to convert an absolute input to a relative output. I have been googling around the website but I haven't found any clue how to do this yet.
I will write a small example to clarify the meaning of my question
Simplified example input
<object value="5"/>
<object value="6"/>
<object value="8"/>
<object value="16"/>
Simplified example output
<difference value ="5"/>
<difference value ="1"/>
<difference value ="2"/>
<difference value ="8"/>
So... I wish to use the current and the previous object (input) to calculate the difference (output)

Hi
Use a two input transformation, one new, one old.
