[SOLVED] MQTT 2.4 and dimmer

My MQTT enabled dimmer uses values 0…255 to set the brightness from 0% to 100%.
Setting “Absolute minimum” and “Absolute maximum” values in the Thing’s channel transforms correctly the state value to percentage.
However, how is the reverse transformation for the command value? When I use %s for the command, values between 0 and 100 are transferred. Is there any other variable as %s?

Seems to be fixed in openHAB 2.5.0.M1 Milestone Build
