At the very least this:
public class FromPlToMovLinKRLAttributes:GH_Attributes<FromPlToMovLinKRL>
public class FromPlToMovLinKRLAttributes:GH_ComponentAttributes<FromPlToMovLinKRL>
But I find it very suspicious. Someone is assigning standard
GH_ComponentAttributes to your component, otherwise it would not look correct at first. I understand why your component looks like a blue/green box, but typically the only way Grasshopper assigns attributes to objects is by calling the
CreateAttributes method, which in your case should always result in your blue/green box.
I’m digging through the entire code-base now, trying to find a way in which different attributes might be assigned by some object other than the component. It will take a while.
