Long time I posted on the board, but I found some issues when grouping and saving into the library.
If you take the diagramdemo which is provided, I made three diagramblocks and group them. Then I take another two and group them as well. Then I go into the screen where you can save it in the library, I choose category and name of item. (I know that it does a GroupSelectedBlocks and a serializestring)
When I load back the saved item and press on ungroup, my items are not grouped correctly anymore.
Any help is most welcome
