Left and Right functions

Hi

Did anyone get an answer to this?

I have a rule that works perfectly, until the incoming string is more than 64 characters, then the recieving device just rejects the whole command.

Current rule

rule "Sonos to Velbus Memo text"
when
Item Sonos_Title changed
then

Velbus_memo_text.sendCommand(Sonos_Title.state)

end

Should something like this work? (In openHAB2 2.5 M1)

rule "Sonos to Velbus Memo text - Left 63"
when
Item Sonos_Title changed
then

Velbus_memo_text.sendCommand(Sonos_Title.state.toString.left(63))

end
