Right, that's the problem here. My take is to ignore the layers in that case 
and put the grouped objects all together on the target layer. Simplicity first, 
meaning it's weird if we automatically create layers. If users need to keep the 
structure we have to implement an extra function but my advice is to copy the 
layer(s) with grouped objects and delete unneeded objects. That brings me to 
the requirement of multi-selection of layers.

Hi all,
I have only answered to list.

Doubt that an internal object identification by name is a good idea. You have 
to suppress identical naming and on paste you add a number (Foo1). But that's 
up to development. From the user perspective I don't care.


The user will be able to change display name without affecting the 
internal name. The current solution of "paste always to the active 
layer" produces the problem described in the linked comment".





We need advise, what should happen, if an object is copy into a 
different page of the same document. In the end of the project it will be possible, 
that pages of a document may have different layer-sets. Similar problem is  pasting 
into a different document. Possible actions e.g.
a) paste all into the active layer
b) paste objects into that layer, which has the same name, and on the active 
layer in case no such layer exists
c) paste objects into that layer, which has the same name, and generate a new 
layer in case no such layer exists.
d) others?


As an example

Page 1
 Layer "Foo"
  Shape_1
  Group_1
   Shape_2
   Shape_3
 Layer_Bar
Page 2
 Default layer

If you copy/move Shape_1 from Layer_Foo to Page 2 it should affect only this 
object, and Shape_1 is placed on the default layer.


So do not generate a new layer "Foo" on page 2.

 If the user copy/pastes a group, all objects are taken.

That is the purpose of a group. But you can have this situation
Page 1
  Layer "Foo"
   Shape_1
   Shape_2 (contained in group1)
  Layer_Bar
   Shape_3 (contained in group1)
 Page 2
  Default layer

So group1 contains shapes from different layers, see description in the 
linked comment.


 And we need a separate function for the layer. So copying Layer_Bar

There is currently no option to copy a layer. We have not yet considered 
such option.


 into page 2 adds it likewise when creating a new layer and pasting 
just all objects from Layer_Bar. Differently to the ctrl+a,ctrl+c/x 
interaction, I would include all hidden elements too for the layer copy 
action..


There exists no hidden elements in Draw/Impress. Visible/Not-Visible is 
a property of the layer not of the element.


But you are right, copying an entire layer sound like a useful feature. 
That would be an option "paste and force a new layer for the clipboard 
content".


Kind regards
Regina
