Initialization of an agent's geometry

[minhduc0711]

Hello, I am trying to define a setter of a skill's attribute like this:

// Java
@setter(LANES)
public static void setLanes(final IAgent road, final int numLanes) {
     int numSegments = road.getInnerGeometry().getNumPoints() - 1;
     ....
}

But I get a NullPointerException at getInnerGeometry() when trying to create an agent:

// GAML
create road {
     lanes <- 3;
}

I assume that's because an agent's geometry is not initialized until all attributes are set.
Can I somehow change this initialization order, or is there another possible workaround?

Turns out it was a really obvious cause, I forgot to initialize the shape var...

// GAML
create road {
    shape <- polyline([a,b]);
    lanes <- 3;
}

Edit: actually the problem still exists :|
