Document copied for Picture viewer doesnt copy contents of child of a TagData

[ECHekman]

I am encountering a problem when rendering to picture viewer.
I have two plugins, a TagData and a NodeData as its child.
I also created a link from the TagData to the NodeData for easy access
However when the document is copied and sent to the picture viewer renderer there are two issues.

1. The link is not copied
2. The contents of the NodeData basecontainer are not copied over

The copied TagData does have a child object with my type, so it does exist

Here is how I connect the two plugins

Bool MyTagData::Init(GeListNode* node, Bool isCloneInit)
{
    BaseTag* tag = (BaseTag*)node;
    BaseContainer *data = tag->GetDataInstance();
    BaseList2D* mynodedata= BaseList2D::Alloc(ID_MY_NODEDATA); // Creating my MyNodeData
    mynodedata->InsertUnderLast(node); //Add as mynodedata as a child to mytagdata
    data->SetLink(MYTAG_NODEDATA_INK, mynodedata); //Add link for easy access
    return true;
}

This basically works in all situations, except when sending it to the picture viewer for rendering.
I feel like im missing something, but i cant find what in the documentation
