Shaderlink not displaying

I have a ObjectPlugin with a ShaderLink in the Res file.
I can set the link, but the link is not displayed. Also when reading the Link I get None, although I set it to a Noise Shader in Init();
When I set the Link by hand it works and I can read it.

Here the code.

import c4d, os, sys
from c4d import bitmaps, documents, gui, modules,  plugins, utils
  
#shaderlink test
  
SHADER      = 9001    
  
class ShaderlinkTest(plugins.ObjectData) :
    def __init__(self) :
        self.lastframe = False
  
    def Init(self, op) :
        #self.InitAttr(op, link, [SHADER])
        shd = c4d.BaseList2D(c4d.Xnoise)
        op[SHADER]= shd
        print "shd - op[SHADER]: ", shd, op[SHADER]		#seems ok
        return True
  
    def GetVirtualObjects(self, node, hierarchyhelp) :
        print "Shader: ", node[SHADER]				#always None if not set by hand.
        return None
            
if __name__ == "__main__":
  
    pluginstr = "Shaderlink v01"
  
    path, file = os.path.split(__file__)
    bmp = bitmaps.BaseBitmap()
    bmp.InitWith(os.path.join(path, "res", "twe.png"))
                       
    okyn = plugins.RegisterObjectPlugin(id = 1029726, str = pluginstr, g = ShaderlinkTest, description = "twe", icon = bmp, info = c4d.OBJECT_GENERATOR)
  

Here the Res file.

CONTAINER twe
{
	NAME twe;
    INCLUDE Obase;
    
    GROUP PARAMS
    {
        BOOL SHOWCON {}
        SHADERLINK SHADER { }
    }   
		
}

Again, I did not read other posts good enough.
I have to store the shader first of course.

op.InsertShader(shd)

This now works.
