Calling certain external component functions works on OpenComputer through the 'component' variable, but the same functions return "nil" if called through a relay with a ComputerCraft computer

Here's a ME Controller with a single item in its drives

It's being invoked fine on OC

But here's on ComputerCraft

• canExtract():bool => works
• canReceive():bool => works
• getAvgPowerInjection():float => works
• getAvgPowerInjection():float => works
• getCpus():table => always nil
• getCraftables():table => always nil
• getEnergyStored():float => works
• getItemsInNetwork():table => always nil

It seems like tables do not make it through the relay.

For what it's worth, the relay is fully upgraded with a tier 3 disk, tier 3 CPU and a tier 3.5 ram stick so the serialized data should have room ?

The whole setup is like so (yes it's powered)

Obvious disclaimer that I'm not super well-versed in OC internals, so may be misreading things...

Looking at RelayPeripheral, it appears that the result of Component.invoke is returned immediately without any intermediate conversion:

OpenComputers/src/main/scala/li/cil/oc/integration/computercraft/RelayPeripheral.scala

Line 60 in 310db04

component.invoke(method, fakeContext, arguments.drop(2): _*)

However, some methods like getItemsInNetwork return an array of values, rather than a map. CC does not support this, and so it is skipped and null/nil is returned.

I'll have a look at expanding the conversion logic on CC:T's side - it's something I've been meaning to do for a while. That said, it's probably worth adding further conversions on the OC side, so that all versions of MC/CC are supported.

@SquidDev you mean you'd like to see us convert an array response from that invoke and convert it to a map before returning from callRemote?

[SquidDev]

@payonel I'm afraid yes. I suspect you'll need to handle all of the cases in ScalaClosure.toLuaValue, as you'll also have arrays inside maps. Sorry!

OpenComputers/src/main/scala/li/cil/oc/util/ScalaClosure.scala

Lines 48 to 54 in e452b1f

	case value: Array[_] => toLuaList(value)
	case value: Value if Settings.get.allowUserdata => LuaValue.userdataOf(value)
	case value: Product => toLuaList(value.productIterator.toIterable)
	case value: Seq[_] => toLuaList(value)
	case value: java.util.Map[_, _] => toLuaTable(value.toMap)
	case value: Map[_, _] => toLuaTable(value)
	case value: mutable.Map[_, _] => toLuaTable(value.toMap)

Any updates on this?
