LUA Script based vessel: Thruster not working

[astrosammy]

Ok, I've been trying to get this running for a hour, but somehow the Probe doesn't want me to get it working.

I've created a thruster and added it to the main group. As you can see, a fueltank is also created.
But when I try to ignite it, nothing is happening.

I checked the number of thrusters in the main group inside orbiter, and it was 1. Then I checked the thrust of this thruster, and it was correct.
Looking at the example "ScriptPB.cfg", it looks like everything is right.

function clbk_setclasscaps(cfg)
    ...
    
    Prop1 = vi:create_propellantresource(1258.7)
    
    engparam = {pos={x=0,y=0,z=0}, dir={x=0,y=1,z=0}, maxth0=8450, isp0=2658.51, ispr=1471.5}
    eng1 = vi:create_thruster(engparam) 
    maineng=vi:create_thrustergroup({eng1},THGROUP.MAIN)
    
    ...
end

And 4 minutes later it works!

I added "engparam.hprop = Prop1"

But the orbiter script manual says that a thruster will take fuel from any resource if hprop is not set... strange...

Where did you read that? Mine says

If no propellant resource handle is provided, the thruster is not connected to a propellant resource and cannot be activated until connected.

Looks like I should read more carefully...
