Data Exchange API: You seem to already have tried to get an Actuator Handle on this one.

edit

I have updated my IDF to E+ 9.4, I've updated all exchange handlers adding the "state" variable, but now it throws the following warning too many times:

** Warning ** Data Exchange API: You seem to already have tried to get an Actuator Handle on this one.
**   ~~~   ** Occurred for componentType='SCHEDULE:COMPACT', controlType='SCHEDULE VALUE', uniqueKey='N1LAB_TSP'.
**   ~~~   ** The getActuatorHandle function will still return the handle (= 21) but caller should take note that there is a risk of overwritting.

I check the output results and compare with the results in E+ 9.3 and are not the same. I don't understand where is the problem, Any ideas.
