AE2 integration failure with crafting_state event

[drowfx]

When I use AE2 autocrafting through with OpenComputers (MC1.7.10-1.5.22.46) and OpenPeripheralIntegration (1.7.10-0.5), when I listen to the crafting_state event emitted when an autocrafting job completes, I get a
[Server thread/WARN] [OpenComputers]: Trying to push signal with an unsupported argument of type java.util.HashMap
in the server log, and the first argument of the event (the "requestedStack" from https://github.com/OpenMods/OpenPeripheral-Integration/blob/master/src/main/java/openperipheral/integration/appeng/CraftingRequester.java#L40) is nil in my LUA code.

I am using appliedenergistics2-rv3-beta-6.

EDIT:
The expected result would be a LUA table containing the fingerprint of the crafted item etc. It is working with ComputerCraft (1.75).

Seems to be OpenComputers issue, waiting for answer.
