Dino Ghilardi (dino-ghilardi) wrote on 2019-05-27: eeschema hierarchical sheet copy-paste

Using copy-paste on a child sheet block to have two sheets coming from the same file creates an empty sheet, possibly loosing data.

To reproduce the bug:

1 Create a project
2 Create a new hierarchical sheet (using "Add a hierarchical sheet").
2.5 Put something inside it (components, connections, etc.)
3 Go back to the parent sheet.
4 use copy-paste to create a new hierarchical sheet. It has the same file reference (correct)
5 if you enter the new created sheet it is empty.
if you save the schematic now you loose the old child sheet content. It seems it is overwritten by the new empty one having the same filename.

6: Workaround: If you edit the properties of the new block in the parent sheet (shortcut E or right-click->properties), do not change anything and confirm: a dialog asks for confirm, then the child sheet loads the correct schematic in it.

Quicker (more dangerous) way to reproduce the bug:
-Open a schematic (that has a backup somewhere) with some hierarchical sub-sheet
-copy-paste one of them
-save-->...data lost.
