title: CEP 5.4.3, not triggering basic condition
body: <p>using CEP i'm trying to make a basic example of communication between Proton and Orion.
  I simply want Proton to receive a notification of temperature from Orion and send back a payload changing one boolean attribute if the temperature value is superior or equal to 20.</p>
  
  <p>Here is the definition i'm using.</p>

  <p>I try to create a file while first update is receive but this file is always empty, btw it is correctly create in my directory and change everytime I change definition. The rest payload is never send like the condition is never triggered.</p>
