Geometry Generating Components Preview Problems

[a.khajehee]

I’m trying to create geometry components programmatically.
Using this code I can create almost any component including geometry creating components.
var component = new … whatever geometry component like a simple loft();
component.CreateAttributes();
component.Attributes.Pivot = someCoordinatePivot;
component.Selected
this.OnPingDocument().AddObject(component, true);

However, when I select that component it does not highlight it in the Rhino viewport like components made in a normal way.

@DavidRutten I would really appreciate your guidance on this. This is almost the last thing I need to fix for my plug-in.

Update:
I have used the " RepairParamAssociations" method to fix the problem. But the documentation says “If you stick to regular functions, you shouldn’t have to call this.”
I’m wondering what are the “regular” functions that I should use.
