With Update to 5.1 I get There is no context to infer the closure's argument types from in switch rule

Setup, Configuration and Use Scripts & Rules

After updating to OPENHab 5.1 I have error in one of my rules file:

There is no context to infer the closure’s argument types from. Consider typing the arguments or put the closures into a typed context.

I have narrowed to following rule:

rule “3state”

when

Item My3stateSwitch changed

then

val Boolean log = true

switch (My3stateSwitch.state as Number) {

case  0 : {

  gAllTelevisions?.members.forEach\[sw|

    sw.sendCommand(OFF)

    Thread::sleep(1000)

    if (log) logInfo('rules', ' Regel 3state Fernseher alle aus: ' + sw.name + ' = ' + sw.state.toString())

  \]

}

case  1 : {

  gAllTelevisions?.members.forEach\[sw|

    sw.sendCommand(ON)

    Thread::sleep(1000)

    if (log) logInfo('rules', ' Regel 3state Fernseher alle ein: ' + sw.name + ' = ' + sw.state.toString())

  \]

}

case 2 : {}

}

end

the items definition:

// Televisions

I know there where a lot of changes with OPENhab 5.x but do not find what I have to change to make the rule work again.

OpenHab Version 5.1

openHAB 5.1 - Rules that use members.forEach are ignored because of missing context
2

Based on the error message, I’d say try:

gAllTelevisions?.members.forEach[SwitchItem sw|
3

Thanks, that was the solution!
