I wrote some code to perform 2 node inserts. I added before/after undo
commands and undo/redo of the individual operations seemed to work fine.
But when I enclose the two operations in before/after changeGroup, then
redo doesn't work.
Does anyone know what I'm doing wrong?
To duplicate the issue:
1. copy below xml to clipboard
2. in a new leo outline ctrl-shift-c to paste as nodes
3. highlight the "grouped insert redo test" node
4. ctrl-b to execute it...two new headlines appear as expected
5. ctrl-z to undo it...the two headlines disappear as expected
6. ctrl-shift-z to redo it. The redo doesn't happen and the console
shows this message:
redoGroup oops: expecting bunch.items. bunch.kind = insert
redoGroup g.Bunch()
dirtyVnodeList: []
kind: insert
