Cloning a shader [SOLVED]

I have a material from which I want to copy a shader to a tag with a texture field.
So I get the material, get the shader, clone it and copy it to the tag texture field.

This does not work

    cloneShd = mat1[c4d.MATERIAL_COLOR_SHADER]
    shd = cloneShd.GetClone()

When I do not use a clone it works!

    shd = mat1[c4d.MATERIAL_COLOR_SHADER]

What am I doing wrong here?

Have you inserted the clone into the tag using BaseList2D.InsertShader()?

No, I use it in a VRay tag to set the texture.

tag[c4d.VRAYLIGHTTAG_AREA_RECT_TEX] = shd

Without the clone it works fine. Using a clone, the texture does not seem to be filled.

You have to insert it, else it won't have any connection to the document.

  
shd = mat1[c4d.MATERIAL_COLOR_SHADER].GetClone()   
tag.InsertShader(shd)   
tag[c4d.VRAYLIGHTTAG_AREA_RECT_TEX] = shd

Strange things are happening with this post.

On my  mobile I received a message that a post was added by Yannick saying:

"This is a limitation of the python api.
For such situations the c++ api provides the "AliasTrans" class but the python api does not implement this classand c4datom.getclone() misses the AliasTrans parameter."

Did I quote you correctly Yannick?

Great, it is working now.
I guess when I use the original it is already inserted (somewhere?) and the clone is still to be inserted.

Exactly the shader you create a clone of has already been inserted into the material.
